N-(3-Bromophenyl)-2-((4-(4-chlorophenyl)-5-(pyridin-4-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide CAS 476483-91-7

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-Bromophenyl)-2-((4-(4-chlorophenyl)-5-(pyridin-4-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide.

N-(3-Bromophenyl)-2-((4-(4-chlorophenyl)-5-(pyridin-4-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide (CAS 476483-91-7), molecular formula C21H15BrClN5OS and molecular weight 500.80 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine/bromine substitution, N-(3-Bromophenyl)-2-((4-(4-chlorophenyl)-5-(pyridin-4-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 500.80 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.

CATO manufactures N-(3-Bromophenyl)-2-((4-(4-chlorophenyl)-5-(pyridin-4-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
