4-((3-Bromobenzylidene)amino)-3-(m-tolyl)-1H-1,2,4-triazole-5(4H)-thione CAS 478255-50-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-((3-Bromobenzylidene)amino)-3-(m-tolyl)-1H-1,2,4-triazole-5(4H)-thione.

4-((3-Bromobenzylidene)amino)-3-(m-tolyl)-1H-1,2,4-triazole-5(4H)-thione (CAS 478255-50-4), molecular formula C16H13BrN4S and molecular weight 373.27 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution, 4-((3-Bromobenzylidene)amino)-3-(m-tolyl)-1H-1,2,4-triazole-5(4H)-thione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 373.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
