2-((4-(4-Bromophenyl)-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide CAS 477332-62-0

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

2-((4-(4-Bromophenyl)-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide (CAS 477332-62-0), molecular formula C15H12BrN5OS and molecular weight 390.26 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-((4-(4-Bromophenyl)-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide (C15H12BrN5OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
