3-(4-(4-Ethoxyphenyl)-5-((2-methylbenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine CAS 477330-16-8

Description

The occurrence of 3-(4-(4-Ethoxyphenyl)-5-((2-methylbenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(4-(4-Ethoxyphenyl)-5-((2-methylbenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine (CAS 477330-16-8), molecular formula C23H22N4OS and molecular weight 402.51 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-(4-(4-Ethoxyphenyl)-5-((2-methylbenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine (C23H22N4OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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.

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.
