Chemical Structure

Ethyl 2-acetyl-3-oxobutanoate CAS 603-69-0 chemical structure

Description

Ethyl 2-acetyl-3-oxobutanoate (CAS 603-69-0), molecular formula C8H12O4 and molecular weight 172.18 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Ethyl 2-acetyl-3-oxobutanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 172.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures Ethyl 2-acetyl-3-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.
