SLU-PP-332 is an organic aromatic hydrazone compound with the molecular formula C18H14N2O2 and a molecular weight of approximately 290.3 g/mol. Its molecular architecture contains a hydroxy-substituted benzoyl region connected through a hydrazone linkage to a naphthalene-derived aromatic system.
The structure contains two nitrogen atoms and two oxygen atoms distributed across a hydrazone-hydrazide environment, a carbonyl group and a phenolic hydroxyl group. The combination of two extended aromatic regions, carbonyl functionality, phenolic substitution and nitrogen-containing connectivity provides multiple analytical markers suitable for chromatographic, mass-spectrometric and spectroscopic characterisation.
A defining structural feature of SLU-PP-332 is the presence of a naphthalene ring system. This fused bicyclic aromatic region consists of two condensed benzene rings and represents a substantial portion of the molecule's conjugated aromatic surface.
The naphthalene system provides multiple chemically distinguishable aromatic proton and carbon environments and may contribute strongly to ultraviolet absorption, chromatographic retention and spectroscopic behaviour.
SLU-PP-332 contains a hydroxy-substituted benzoyl region associated with the hydrazide portion of the molecule. This aromatic component combines a phenyl ring with a phenolic hydroxyl substituent and a carbonyl-containing hydrazide functionality.
The combination of these groups provides characteristic aromatic, carbonyl and hydroxyl environments that can support comparative identification using chromatographic and spectroscopic techniques.
The molecular framework of SLU-PP-332 contains a hydrazone-type linkage connecting the benzohydrazide region to the naphthalene-derived portion of the molecule.

The molecular formula C18H14N2O2 reflects a structure containing carbon, hydrogen, nitrogen and oxygen distributed across several chemically distinct structural regions.
The combination of aromatic, phenolic, carbonyl and nitrogen-containing structural elements provides multiple analytical markers for comparative compound identification.
SLU-PP-332 contains a phenolic hydroxyl group attached to the benzene-derived aromatic region. This functionality introduces a polar O-H environment into an otherwise extensively aromatic molecular framework.
The phenolic hydroxyl group may contribute characteristic infrared absorption and proton NMR behaviour and can influence solvent interactions, intermolecular association and chromatographic characteristics.
The benzohydrazide-derived region contains a carbonyl group positioned adjacent to the nitrogen-containing hydrazide functionality.
This carbonyl environment provides a characteristic structural marker that may be observed through infrared spectroscopy and carbon NMR and may also influence molecular polarity and intermolecular interactions.
SLU-PP-332 contains two nitrogen atoms within its hydrazone-hydrazide structural region. These nitrogen atoms occupy chemically distinct environments associated with the carbonyl-containing hydrazide functionality and the carbon-nitrogen double-bond system.
The nitrogen-containing region contributes to the molecular polarity and may influence ionisation behaviour and spectroscopic characteristics under different analytical conditions.
The molecule contains two principal aromatic regions: a substituted phenyl ring and an extended fused naphthalene system. These aromatic components are connected through the hydrazone-hydrazide framework.
This arrangement creates multiple aromatic proton and carbon environments that can assist structural verification through NMR, ultraviolet spectroscopy and chromatographic comparison.
SLU-PP-332 contains an extended arrangement of aromatic and unsaturated structural elements. The naphthalene system, substituted phenyl ring and hydrazone region collectively contribute to the conjugated character of the molecule.
This conjugation can influence ultraviolet-visible absorption characteristics and provides an analytically useful structural feature for comparative spectroscopic examination.
SLU-PP-332 contains two nitrogen atoms and two oxygen atoms distributed across the hydrazone, carbonyl and phenolic regions of the molecule.
One oxygen atom is present within the carbonyl functionality and the second is present as the phenolic hydroxyl group. The two nitrogen atoms form the central hydrazone-hydrazide connectivity between the aromatic regions.
The phenolic hydroxyl group and hydrazide-associated nitrogen environment provide potential hydrogen-bond donor sites, while the carbonyl oxygen and selected nitrogen environments may contribute hydrogen-bond acceptor character.
This combination can influence solvent interactions, chromatographic behaviour, solid-state organisation and sample-preparation characteristics.
SLU-PP-332 combines a substantial aromatic surface area with polar hydroxyl, carbonyl and nitrogen-containing functionalities. This creates a mixed molecular character involving both hydrophobic aromatic regions and more polar functional groups.
This balance is relevant when evaluating solvent selection, sample preparation and reversed-phase chromatographic conditions.
The registered structure of SLU-PP-332 contains defined geometry associated with the hydrazone carbon-nitrogen double bond. This geometric configuration forms part of the registered chemical identity of the compound.
Geometric identity may be relevant during structural characterisation and comparison with authenticated reference material, particularly when spectroscopic techniques are used to distinguish alternative configurations.
The fused naphthalene ring and phenyl ring provide relatively rigid aromatic regions, while the connecting hydrazone-hydrazide functionality permits a more limited range of conformational arrangements.
The combination of rigid aromatic regions and heteroatom-containing connectivity may influence molecular planarity, intermolecular interactions and chromatographic behaviour.
Under reversed-phase liquid chromatographic conditions, retention may be influenced by the extensive naphthalene and phenyl aromatic surface area together with the phenolic hydroxyl, carbonyl and nitrogen-containing functionalities.
Retention time and peak shape may vary according to mobile-phase composition, gradient conditions, stationary-phase chemistry, temperature, pH and sample concentration.
LC-based methods may be used for qualitative identity comparison, purity profiling and retention-time verification of SLU-PP-332 reference material.
The combination of extended aromatic surface area and several polar functional groups may require optimisation of mobile-phase composition and stationary-phase chemistry for suitable retention and peak symmetry.
With a molecular weight of approximately 290.3 g/mol, SLU-PP-332 falls within a mass range suitable for routine LC-MS analysis. Appropriate ionisation conditions may support detection of protonated, deprotonated or adduct-associated molecular species depending on solvent composition and instrument parameters.
Fragmentation may involve the hydrazone linkage, benzohydrazide region or naphthalene-associated portion of the molecule and may support structural confirmation when compared with authenticated reference data.
Proton NMR analysis may show characteristic resonances associated with the naphthalene ring system, substituted phenyl ring, hydrazone-associated proton environment, phenolic hydroxyl group and nitrogen-associated proton environments.
Carbon NMR analysis may provide distinguishable signals corresponding to naphthalene carbons, substituted phenyl carbons, the hydrazone-associated carbon environment and the carbonyl carbon.
Infrared analysis may reveal characteristic absorption features associated with the carbonyl group, phenolic O-H environment, nitrogen-associated N-H environment, carbon-nitrogen bonding and aromatic C-H bonds.
The combination of carbonyl, hydroxyl and nitrogen-containing functionalities provides several potentially useful infrared markers for comparative structural characterisation.
The extended aromatic and conjugated systems of SLU-PP-332 may support ultraviolet-based chromatographic detection. Suitable detection wavelengths should be selected according to measured absorbance characteristics and validated laboratory methods.
