Chemical Structure

Ethyl 4-(bromomethyl)-5,5-dimethyl-2-oxo-2,5-dihydrofuran-3-carboxylate CAS 90261-67-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 4-(bromomethyl)-5,5-dimethyl-2-oxo-2,5-dihydrofuran-3-carboxylate.

CATO supplies Ethyl 4-(bromomethyl)-5,5-dimethyl-2-oxo-2,5-dihydrofuran-3-carboxylate (CAS 90261-67-9), a certified reference material (molecular formula C10H13BrO4, MW 277.11 g/mol) for analytical method development and quality control.

The molecular framework of Ethyl 4-(bromomethyl)-5,5-dimethyl-2-oxo-2,5-dihydrofuran-3-carboxylate (C10H13BrO4) 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 Ethyl 4-(bromomethyl)-5,5-dimethyl-2-oxo-2,5-dihydrofuran-3-carboxylate 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.
