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.
Ethyl 4,4-dibromo-2,2-dimethyl-3-oxobutanoate (CAS 151556-85-3) is a high-purity analytical reference standard with the molecular formula C8H12Br2O3 and a molecular weight of 315.99 g/mol.
The molecular framework of Ethyl 4,4-dibromo-2,2-dimethyl-3-oxobutanoate (C8H12Br2O3) 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.
As a certified reference material (CRM), Ethyl 4,4-dibromo-2,2-dimethyl-3-oxobutanoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
