Description
As a certified reference material (CRM), N-Carbobenzoxy-DL-Leucine 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.
N-Carbobenzoxy-DL-Leucine (CAS 3588-60-1), molecular formula C14H19NO4 and molecular weight 265.30 g/mol, is a CATO reference standard with documented purity and traceability.
N-Carbobenzoxy-DL-Leucine (C14H19NO4) contains a nitrogen-containing heterocyclic scaffold, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
