N-(4-nitrophenyl)-2-((4-phenyl-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide CAS 332385-32-7

Description

The occurrence of N-(4-nitrophenyl)-2-((4-phenyl-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N-(4-nitrophenyl)-2-((4-phenyl-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide (CAS 332385-32-7), molecular formula C21H16N6O3S and molecular weight 432.46 g/mol, is a CATO reference standard with documented purity and traceability.

N-(4-nitrophenyl)-2-((4-phenyl-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide (C21H16N6O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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-(4-nitrophenyl)-2-((4-phenyl-5-(pyridin-3-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.
