SLU-PP-332
SLU-PP-332 is a synthetic small molecule — not a peptide — an acylhydrazone (4-hydroxy-N'-(naphthalen-2-ylmethylene)benzohydrazide) built from a naphthalen-2-yl group and a 4-hydroxybenzoyl group joined by a hydrazone linkage.
SLU-PP-332 is a small molecule — an acylhydrazone (aroylhydrazone) — not a peptide: it contains no amino-acid residues and no peptide bonds, in the same sense that NAD+ is not a peptide.

An acylhydrazone: a naphthalen-2-yl ring joined through a hydrazone (–C=N–NH–) linkage to a 4-hydroxybenzoyl group, systematically named 4-hydroxy-N'-(naphthalen-2-ylmethylene)benzohydrazide. It has no amino-acid backbone, so it carries no sequence and no residue count. The geometry of the C=N hydrazone bond is left unresolved here: the systematic name and some vendor records assert the (E) isomer, but the two PubChem records for this skeleton (CID 5404083 and CID 5338394) carry opposite double-bond geometries, so a machine InChIKey and a 3D conformer are withheld pending a chemist ruling — only the connectivity, which every source agrees on, is asserted.
Reference context
SLU-PP-332 is a synthetic small molecule — not a peptide — an acylhydrazone (4-hydroxy-N'-(naphthalen-2-ylmethylene)benzohydrazide) built from a naphthalen-2-yl group and a 4-hydroxybenzoyl group joined by a hydrazone linkage. It is listed here strictly as an analytical reference entity — it is not sold, stocked, or certified by Lineará, and has no price or certificate of analysis. The data on this page is characterization only: molecular formula C18H14N2O2 and the values computed from it. No biological activity, mechanism, or use is described or implied.

How SLU-PP-332 is characterized
Identity rests on the molecular formula and mass. Electrospray mass spectrometry (ESI-MS) measures the mass-to-charge ratio of the intact molecule; the average and monoisotopic masses are computed from the verified formula and cross-check the composition. The molecular formula and the scaffold noted above define the composition.
