CATO supplies [3-(4-Chloro-benzyl)-2,5-dioxo-pyrrolidin-1-yl]-acetic acid (CAS 332849-48-6), a certified reference material (molecular formula C13H12ClNO4, MW 281.69 g/mol) for analytical method development and quality control.
[3-(4-Chloro-benzyl)-2,5-dioxo-pyrrolidin-1-yl]-acetic acid (C13H12ClNO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
