The occurrence of Ethyl 4-bromo-2,2-dimethyl-3-oxobutanoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 4-bromo-2,2-dimethyl-3-oxobutanoate (CAS 63891-88-3), molecular formula C8H13BrO3 and molecular weight 237.09 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 4-bromo-2,2-dimethyl-3-oxobutanoate (C8H13BrO3) 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 4-bromo-2,2-dimethyl-3-oxobutanoate 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.
