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 5-bromo-4-methylbenzo[d]isoxazole-3-carboxylate.
Ethyl 5-bromo-4-methylbenzo[d]isoxazole-3-carboxylate (CAS 854015-42-2) is a high-purity analytical reference standard with the molecular formula C11H10BrNO3 and a molecular weight of 284.11 g/mol.
The molecular framework of Ethyl 5-bromo-4-methylbenzo[d]isoxazole-3-carboxylate (C11H10BrNO3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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 Ethyl 5-bromo-4-methylbenzo[d]isoxazole-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.
