Chemical Structure
Description
Isopropyl 2,3-dihydro-1H-pyrrolizine-1-carboxylate (CAS 66635-71-0) is a high-purity analytical reference standard with the molecular formula C11H15NO2 and a molecular weight of 193.24 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Isopropyl 2,3-dihydro-1H-pyrrolizine-1-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 193.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), Isopropyl 2,3-dihydro-1H-pyrrolizine-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.
