Chemical Structure
Description
CATO supplies Benzoic acid, 4-bromo-3-(methoxy-d3)- (CAS 1620677-57-7), a certified reference material (molecular formula C8H4D3BrO3, MW 234.06 g/mol) for analytical method development and quality control.
The molecular framework of Benzoic acid, 4-bromo-3-(methoxy-d3)- (C8H4D3BrO3) is characterized by deuterium isotope labeling, 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.
As a certified reference material (CRM), Benzoic acid, 4-bromo-3-(methoxy-d3)- 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.
