Chemical Structure
Description
CATO supplies 2-(5-Bromo-2-oxochroman-4-yl)acetic acid (CAS 1334499-95-4), a certified reference material (molecular formula C11H9BrO4, MW 285.09 g/mol) for analytical method development and quality control.
The molecular framework of 2-(5-Bromo-2-oxochroman-4-yl)acetic acid (C11H9BrO4) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-(5-Bromo-2-oxochroman-4-yl)acetic 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.
