3-{[(4-bromophenyl)methanesulfinyl]methyl}-5-{[(2-chloro-6-fluorophenyl)methyl]sulfanyl}-4-phenyl-4H-1,2,4-triazole CAS 344274-87-9

Description

As a certified reference material (CRM), 3-{[(4-bromophenyl)methanesulfinyl]methyl}-5-{[(2-chloro-6-fluorophenyl)methyl]sulfanyl}-4-phenyl-4H-1,2,4-triazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

3-{[(4-bromophenyl)methanesulfinyl]methyl}-5-{[(2-chloro-6-fluorophenyl)methyl]sulfanyl}-4-phenyl-4H-1,2,4-triazole (CAS 344274-87-9), molecular formula C23H18BrClFN3OS2 and molecular weight 550.89 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, fluorine/chlorine/bromine substitution, 3-{[(4-bromophenyl)methanesulfinyl]methyl}-5-{[(2-chloro-6-fluorophenyl)methyl]sulfanyl}-4-phenyl-4H-1,2,4-triazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 550.89 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
