Description
As a certified reference material (CRM), N,N'-Bis(salicylidene)-1,2-propanediamine 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,N'-Bis(salicylidene)-1,2-propanediamine (CAS 94-91-7), molecular formula C17H18N2O2 and molecular weight 282.34 g/mol, is a CATO reference standard with documented purity and traceability.
N,N'-Bis(salicylidene)-1,2-propanediamine (C17H18N2O2) contains a steroid core, an amide 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 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.
