3-{[(4-bromophenyl)methanesulfinyl]methyl}-5-{[(4-chlorophenyl)methyl]sulfanyl}-4-phenyl-4H-1,2,4-triazole CAS 344274-99-3

Description

3-{[(4-bromophenyl)methanesulfinyl]methyl}-5-{[(4-chlorophenyl)methyl]sulfanyl}-4-phenyl-4H-1,2,4-triazole (CAS 344274-99-3), molecular formula C23H19BrClN3OS2 and molecular weight 532.90 g/mol, is a CATO reference standard with documented purity and traceability.

3-{[(4-bromophenyl)methanesulfinyl]methyl}-5-{[(4-chlorophenyl)methyl]sulfanyl}-4-phenyl-4H-1,2,4-triazole (C23H19BrClN3OS2) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 3-{[(4-bromophenyl)methanesulfinyl]methyl}-5-{[(4-chlorophenyl)methyl]sulfanyl}-4-phenyl-4H-1,2,4-triazole 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.
