1-palmitoyl-2-stearoyl-(16-doxyl)-sn-glycero-3-phosphocholine 216491-65-5 CAS 216491-65-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-palmitoyl-2-stearoyl-(16-doxyl)-sn-glycero-3-phosphocholine 216491-65-5.

1-palmitoyl-2-stearoyl-(16-doxyl)-sn-glycero-3-phosphocholine 216491-65-5 (CAS 216491-65-5), molecular formula C46H90N2O10P and molecular weight 862.19 g/mol, is a CATO reference standard with documented purity and traceability.

1-palmitoyl-2-stearoyl-(16-doxyl)-sn-glycero-3-phosphocholine 216491-65-5 (C46H90N2O10P) contains an amide group, a phosphate ester group, a carboxylic acid 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 1-palmitoyl-2-stearoyl-(16-doxyl)-sn-glycero-3-phosphocholine 216491-65-5 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.
