CATO supplies 2-((4-(2,4-Dichlorophenyl)-5-((naphthalen-1-ylamino)methyl)-4H-1,2,4-triazol-3-yl)thio)acetohydrazide (CAS 1306738-78-2), a certified reference material (molecular formula C21H18Cl2N6OS, MW 473.38 g/mol) for analytical method development and quality control.
Structurally, 2-((4-(2,4-Dichlorophenyl)-5-((naphthalen-1-ylamino)methyl)-4H-1,2,4-triazol-3-yl)thio)acetohydrazide (C21H18Cl2N6OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 473.38 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
