Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
tert-Butyl (S)-3-isobutyrylpyrrolidine-1-carboxylate (CAS 2136696-21-2) is a high-purity analytical reference standard with the molecular formula C13H23NO3 and a molecular weight of 241.33 g/mol.
tert-Butyl (S)-3-isobutyrylpyrrolidine-1-carboxylate (C13H23NO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), tert-Butyl (S)-3-isobutyrylpyrrolidine-1-carboxylate 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.
