Chemical Structure
Description
6-Bromo-8-methoxy-2H-chromene-3-carboxylic acid methyl ester (CAS 885271-18-1) is a high-purity analytical reference standard with the molecular formula C12H11BrO4 and a molecular weight of 299.12 g/mol.
The molecular framework of 6-Bromo-8-methoxy-2H-chromene-3-carboxylic acid methyl ester (C12H11BrO4) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 6-Bromo-8-methoxy-2H-chromene-3-carboxylic acid methyl ester 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.
