Description
CATO manufactures 3-Bromo-2-oxopropanalDISCONTINUED 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.
3-Bromo-2-oxopropanalDISCONTINUED (CAS 81371-84-8), molecular formula C3H3BrO2 and molecular weight 150.96 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-Bromo-2-oxopropanalDISCONTINUED (C3H3BrO2) 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 150.96 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.
