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 Benzoic acid, 4-bromo-3-(3-buten-1-yloxy)-, methyl ester.
Benzoic acid, 4-bromo-3-(3-buten-1-yloxy)-, methyl ester (CAS 1781270-44-7), molecular formula C12H13BrO3 and molecular weight 285.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Benzoic acid, 4-bromo-3-(3-buten-1-yloxy)-, methyl ester (C12H13BrO3) 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).
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 Benzoic acid, 4-bromo-3-(3-buten-1-yloxy)-, 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.
