5-Bromo-2-(methylsulfonyl)-4,5-dihydrooxazole CAS 1380571-67-4

Description

The occurrence of 5-Bromo-2-(methylsulfonyl)-4,5-dihydrooxazole is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Bromo-2-(methylsulfonyl)-4,5-dihydrooxazole (CAS 1380571-67-4), molecular formula C4H6BrNO3S and molecular weight 228.06 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Bromo-2-(methylsulfonyl)-4,5-dihydrooxazole (C4H6BrNO3S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. 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. 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 5-Bromo-2-(methylsulfonyl)-4,5-dihydrooxazole 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.
