Description
CATO manufactures 1-Bromo-4-oxo-3-oxabicyclo[3.1.0]hexane-6-carboxylic acid 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.
CATO supplies 1-Bromo-4-oxo-3-oxabicyclo[3.1.0]hexane-6-carboxylic acid (CAS 89891-30-5), a certified reference material (molecular formula C6H5BrO4, MW 221.01 g/mol) for analytical method development and quality control.
The molecular framework of 1-Bromo-4-oxo-3-oxabicyclo[3.1.0]hexane-6-carboxylic acid (C6H5BrO4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
