2-((5-(2,4-Dichlorophenyl)-4-phenyl-4h-1,2,4-triazol-3-yl)thio)acetic acid CAS 158773-87-6

Description

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.

CATO supplies 2-((5-(2,4-Dichlorophenyl)-4-phenyl-4h-1,2,4-triazol-3-yl)thio)acetic acid (CAS 158773-87-6), a certified reference material (molecular formula C16H11Cl2N3O2S, MW 380.25 g/mol) for analytical method development and quality control.

The molecular framework of 2-((5-(2,4-Dichlorophenyl)-4-phenyl-4h-1,2,4-triazol-3-yl)thio)acetic acid (C16H11Cl2N3O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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