Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Sodium palmitoyl-L-prolinate (CAS 58725-33-0), molecular formula C21H38NO3Na and molecular weight 375.53 g/mol, is a CATO reference standard with documented purity and traceability.
Sodium palmitoyl-L-prolinate (C21H38NO3Na) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), Sodium palmitoyl-L-prolinate 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.
