Chemical Structure

1-Bromo-2-ethenyl-4,5-dimethoxybenzene CAS 5293-43-6 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 1-Bromo-2-ethenyl-4,5-dimethoxybenzene.

1-Bromo-2-ethenyl-4,5-dimethoxybenzene (CAS 5293-43-6), molecular formula C10H11BrO2 and molecular weight 243.10 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-Bromo-2-ethenyl-4,5-dimethoxybenzene (C10H11BrO2) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 1-Bromo-2-ethenyl-4,5-dimethoxybenzene 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.
