Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 209.04 g/mol gives Ethyl 3-bromo-4-oxobutanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 3-bromo-4-oxobutanoate (CAS 56580-46-2) is a high-purity analytical reference standard with the molecular formula C6H9BrO3 and a molecular weight of 209.04 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, Ethyl 3-bromo-4-oxobutanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 209.04 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 3-bromo-4-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.
