Chemical Structure
Description
Benzyl N-(diphenylmethylene)-L-serinate (CAS 145362-72-7) is a high-purity analytical reference standard with the molecular formula C23H21NO3 and a molecular weight of 359.42 g/mol.
Benzyl N-(diphenylmethylene)-L-serinate (C23H21NO3) contains a steroid core, an amide 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.
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 N-(diphenylmethylene)-L-serinate 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.
