Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(3-chloro-2-methylphenyl)-2-((5-(2-chlorophenyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)acetamide.
N-(3-chloro-2-methylphenyl)-2-((5-(2-chlorophenyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)acetamide (CAS 332948-91-1) is a high-purity analytical reference standard with the molecular formula C23H18Cl2N4OS and a molecular weight of 469.39 g/mol.
The molecular framework of N-(3-chloro-2-methylphenyl)-2-((5-(2-chlorophenyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)acetamide (C23H18Cl2N4OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, 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 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.
