Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, 1-octadecanoyl-2--(5Z,8Z,11Z,14Z-eicosatetraenoyl)-sn-glycero-3-phospho-L-serine (sodium salt) 1-stearoyl-2-arachidonoyl-sn-glycero-3-phospho-L-serine (sodium salt) 18:0-20:4 PS 474967-15-2 PS(18:0/20:4(5Z,8Z,11Z,14Z)) SAPS is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 834.06 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

1-octadecanoyl-2--(5Z,8Z,11Z,14Z-eicosatetraenoyl)-sn-glycero-3-phospho-L-serine (sodium salt) 1-stearoyl-2-arachidonoyl-sn-glycero-3-phospho-L-serine (sodium salt) 18:0-20:4 PS 474967-15-2 PS(18:0/20:4(5Z,8Z,11Z,14Z)) SAPS (CAS 474967-15-2) is a high-purity analytical reference standard with the molecular formula C44H77NO10PNa and a molecular weight of 834.06 g/mol.

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--(5Z,8Z,11Z,14Z-eicosatetraenoyl)-sn-glycero-3-phospho-L-serine (sodium salt) 1-stearoyl-2-arachidonoyl-sn-glycero-3-phospho-L-serine (sodium salt) 18:0-20:4 PS 474967-15-2 PS(18:0/20:4(5Z,8Z,11Z,14Z)) SAPS 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.
