Description

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.

1-octadecanoyl-2--(5Z,8Z,11Z,14Z-eicosatetraenoyl)-sn-glycero-3-phosphate (sodium salt) 1-stearoyl-2-arachidonoyl-sn-glycero-3-phosphate (sodium salt) 18:0-20:4 PA 322647-61-0 PA(18:0/20:4(5Z,8Z,11Z,14Z)) SAPA (CAS 322647-61-0) is a high-purity analytical reference standard with the molecular formula C41H72O8PNa and a molecular weight of 746.98 g/mol.

Based on its molecular formula C41H72O8PNa, 1-octadecanoyl-2--(5Z,8Z,11Z,14Z-eicosatetraenoyl)-sn-glycero-3-phosphate (sodium salt) 1-stearoyl-2-arachidonoyl-sn-glycero-3-phosphate (sodium salt) 18:0-20:4 PA 322647-61-0 PA(18:0/20:4(5Z,8Z,11Z,14Z)) SAPA contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 746.98 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
