N-(Naphthalen-2-yl)-N-phenyl-2-((3-(pyridin-3-yl)-1H-1,2,4-triazol-5-yl)thio)acetamide CAS 337488-81-0

Description

N-(Naphthalen-2-yl)-N-phenyl-2-((3-(pyridin-3-yl)-1H-1,2,4-triazol-5-yl)thio)acetamide (CAS 337488-81-0), molecular formula C25H19N5OS and molecular weight 437.52 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, N-(Naphthalen-2-yl)-N-phenyl-2-((3-(pyridin-3-yl)-1H-1,2,4-triazol-5-yl)thio)acetamide (C25H19N5OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 19.0, corresponding to approximately 19 ring(s) or double-bond equivalent(s). With a molecular weight of 437.52 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
