Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,2-DipalMitoyl-sn-glycero-3-ethylphosphocholine, chloride L-1162 328250-18-6.
CATO supplies 1,2-DipalMitoyl-sn-glycero-3-ethylphosphocholine, chloride L-1162 328250-18-6 (CAS 328250-18-6), a certified reference material (molecular formula C42H85NO8PCl, MW 798.57 g/mol) for analytical method development and quality control.
1,2-DipalMitoyl-sn-glycero-3-ethylphosphocholine, chloride L-1162 328250-18-6 (C42H85NO8PCl) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-DipalMitoyl-sn-glycero-3-ethylphosphocholine, chloride L-1162 328250-18-6 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.
