Chemical Structure
Description
CATO supplies (Z)-3-(1-Hydroxyethylidene)pyrrolidine-2,4-dione (CAS 66056-61-9), a certified reference material (molecular formula C6H7NO3, MW 141.12 g/mol) for analytical method development and quality control.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (Z)-3-(1-Hydroxyethylidene)pyrrolidine-2,4-dione is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 141.12 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 (Z)-3-(1-Hydroxyethylidene)pyrrolidine-2,4-dione 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.
