Chemical Structure
Description
3-Bromo-5,5-dimethyl-4,5-dihydroisoxazole (CAS 882697-80-5), molecular formula C5H8BrNO and molecular weight 178.03 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Bromo-5,5-dimethyl-4,5-dihydroisoxazole (C5H8BrNO) is characterized by an amide 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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-Bromo-5,5-dimethyl-4,5-dihydroisoxazole 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.
