Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Benzyl 4-oxoazetidine-2-carboxylate.
CATO supplies Benzyl 4-oxoazetidine-2-carboxylate (CAS 87791-58-0), a certified reference material (molecular formula C11H11NO3, MW 205.21 g/mol) for analytical method development and quality control.
Based on its molecular formula C11H11NO3, Benzyl 4-oxoazetidine-2-carboxylate contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 205.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Benzyl 4-oxoazetidine-2-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.
