2049-67-4 Diethyl pent-2-enedioate 2-Pentenedioic acid, 1,5-diethyl ester 2-Pentenedioic acid, diethyl ester AI3-52336 Diethyl glutaconate EINECS 218-069-2 Glutaconic acid, diethyl ester NSC 62678 (C9H14O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 2049-67-4 Diethyl pent-2-enedioate 2-Pentenedioic acid, 1,5-diethyl ester 2-Pentenedioic acid, diethyl ester AI3-52336 Diethyl glutaconate EINECS 218-069-2 Glutaconic acid, diethyl ester NSC 62678 meets the metrological traceability requirements of ISO/IEC 17025 laboratories.
