Chemical Structure
Description
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.
2-(2-Bromo-4-(sec-butyl)phenoxy)acetic acid (CAS 920122-78-7) is a high-purity analytical reference standard with the molecular formula C12H15BrO3 and a molecular weight of 287.15 g/mol.
The molecular framework of 2-(2-Bromo-4-(sec-butyl)phenoxy)acetic acid (C12H15BrO3) 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).
CATO manufactures 2-(2-Bromo-4-(sec-butyl)phenoxy)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.
