Description
As a certified reference material (CRM), MLi-2, >98% (HPLC) 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.
MLi-2, >98% (HPLC) (CAS 1627091-47-7), molecular formula C21H25N5O2 and molecular weight 379.46 g/mol, is a CATO reference standard with documented purity and traceability.
MLi-2, >98% (HPLC) (C21H25N5O2) contains a steroid core, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
