Chemical Structure
Description
As a certified reference material (CRM), (2R,5R)-1-Benzyl 2-methyl 5-methyl-3-oxopyrrolidine-1,2-dicarboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
(2R,5R)-1-Benzyl 2-methyl 5-methyl-3-oxopyrrolidine-1,2-dicarboxylate (CAS 2761985-32-2), molecular formula C15H17NO5 and molecular weight 291.30 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, (2R,5R)-1-Benzyl 2-methyl 5-methyl-3-oxopyrrolidine-1,2-dicarboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 291.30 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.
