Chemical Structure
Description
1,2-distearoyl-sn-glycero-3-ethylphosphocholine chloride salt 328268-13-9 (CAS 328268-13-9), molecular formula C46H93NO8PCl and molecular weight 854.67 g/mol, is a CATO reference standard with documented purity and traceability.
1,2-distearoyl-sn-glycero-3-ethylphosphocholine chloride salt 328268-13-9 (C46H93NO8PCl) contains an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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), 1,2-distearoyl-sn-glycero-3-ethylphosphocholine chloride salt 328268-13-9 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.
