Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-(Tert-butyl) 3-ethyl (3S,4R)-4-hydroxypyrrolidine-1,3-dicarboxylate (CAS 849935-85-9) is a high-purity analytical reference standard with the molecular formula C12H21NO5 and a molecular weight of 259.30 g/mol.
1-(Tert-butyl) 3-ethyl (3S,4R)-4-hydroxypyrrolidine-1,3-dicarboxylate (C12H21NO5) contains an amino-acid-derived structure, an amide 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).
As a certified reference material (CRM), 1-(Tert-butyl) 3-ethyl (3S,4R)-4-hydroxypyrrolidine-1,3-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.
