Chemical Structure
Description
2-(2-Acetyl-4-bromophenoxy)acetic Acid (CAS 34849-51-9) is a high-purity analytical reference standard with the molecular formula C10H9BrO4 and a molecular weight of 273.08 g/mol.
2-(2-Acetyl-4-bromophenoxy)acetic Acid (C10H9BrO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 2-(2-Acetyl-4-bromophenoxy)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.
