3-(((4-Bromobenzyl)sulfinyl)methyl)-5-((2,6-dichlorobenzyl)thio)-4-ethyl-4H-1,2,4-triazole CAS 344275-04-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(((4-Bromobenzyl)sulfinyl)methyl)-5-((2,6-dichlorobenzyl)thio)-4-ethyl-4H-1,2,4-triazole.

3-(((4-Bromobenzyl)sulfinyl)methyl)-5-((2,6-dichlorobenzyl)thio)-4-ethyl-4H-1,2,4-triazole (CAS 344275-04-3), molecular formula C19H18BrCl2N3OS2 and molecular weight 519.31 g/mol, is a CATO reference standard with documented purity and traceability.

3-(((4-Bromobenzyl)sulfinyl)methyl)-5-((2,6-dichlorobenzyl)thio)-4-ethyl-4H-1,2,4-triazole (C19H18BrCl2N3OS2) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
