Description
CATO manufactures Ethyl 2-bromo-3-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.
CATO supplies Ethyl 2-bromo-3-oxopentanoate (CAS 87943-99-5), a certified reference material (molecular formula C7H11BrO3, MW 223.06 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, Ethyl 2-bromo-3-oxopentanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 223.06 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
