Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including tert-Butyl 3-bromo-2-oxobutanoate.
tert-Butyl 3-bromo-2-oxobutanoate (CAS 61964-76-9), molecular formula C8H13BrO3 and molecular weight 237.09 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H13BrO3, tert-Butyl 3-bromo-2-oxobutanoate contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 237.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
