Chemical Structure
Description
The occurrence of Isopropyl 3-bromo-2-oxopentanoate 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.
Isopropyl 3-bromo-2-oxopentanoate (CAS 27227-92-5), molecular formula C8H13BrO3 and molecular weight 237.09 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, Isopropyl 3-bromo-2-oxopentanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 237.09 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 Isopropyl 3-bromo-2-oxopentanoate 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.
