1-octadecanoyl-2-(4Z,7Z,10Z,13Z,16Z,19Z-docosahexaenoyl)-sn-glycero-3-phospho-L-serine (sodium salt) 1-stearoyl-2-docosahexaenoyl-sn-glycero-3-phospho-L-serine (sodium salt) 18:0-22:6 PS 474943-18-5 PS(18:0/22:6(4Z,7Z,10Z,13Z,16Z,19Z)) (C46H77NO10PNa) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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-octadecanoyl-2-(4Z,7Z,10Z,13Z,16Z,19Z-docosahexaenoyl)-sn-glycero-3-phospho-L-serine (sodium salt) 1-stearoyl-2-docosahexaenoyl-sn-glycero-3-phospho-L-serine (sodium salt) 18:0-22:6 PS 474943-18-5 PS(18:0/22:6(4Z,7Z,10Z,13Z,16Z,19Z)) 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.
