Chemical Structure
Description
Ethyl 2,3-dibromo-3-methylbutanoate (CAS 79405-51-9) is a high-purity analytical reference standard with the molecular formula C7H12Br2O2 and a molecular weight of 287.98 g/mol.
The molecular framework of Ethyl 2,3-dibromo-3-methylbutanoate (C7H12Br2O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 Ethyl 2,3-dibromo-3-methylbutanoate 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.
