Chemical Structure
Description
The occurrence of Methyl 2-Acetoxy-4-bromobutanoate 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.
Methyl 2-Acetoxy-4-bromobutanoate (CAS 76799-57-0), molecular formula C7H11BrO4 and molecular weight 239.06 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Methyl 2-Acetoxy-4-bromobutanoate (C7H11BrO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 239.06 g/mol, it falls into the medium-molecular-weight range. 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.
