Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 257.08 g/mol gives 8-Bromochroman-3-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 8-Bromochroman-3-carboxylic acid (CAS 1691794-69-0), a certified reference material (molecular formula C10H9BrO3, MW 257.08 g/mol) for analytical method development and quality control.
The molecular framework of 8-Bromochroman-3-carboxylic acid (C10H9BrO3) 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 its high hydrophobicity (logP), 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.
CATO manufactures 8-Bromochroman-3-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.
