1,2-di-(5Z,8Z,11Z,14Z-eicosatetraenoyl)-sn-glycero-3-phosphate (sodium salt) 1,2-diarachidonoyl-sn-glycero-3-phosphate (sodium salt) 20:4 PA 474943-33-4 DAPA PA(20:4(5Z,8Z,11Z,14Z)/20:4(5Z,8Z,11Z,14Z)) CAS 474943-33-4 chemical structure

Description

The occurrence of 1,2-di-(5Z,8Z,11Z,14Z-eicosatetraenoyl)-sn-glycero-3-phosphate (sodium salt) 1,2-diarachidonoyl-sn-glycero-3-phosphate (sodium salt) 20:4 PA 474943-33-4 DAPA PA(20:4(5Z,8Z,11Z,14Z)/20:4(5Z,8Z,11Z,14Z)) is closely related to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,2-di-(5Z,8Z,11Z,14Z-eicosatetraenoyl)-sn-glycero-3-phosphate (sodium salt) 1,2-diarachidonoyl-sn-glycero-3-phosphate (sodium salt) 20:4 PA 474943-33-4 DAPA PA(20:4(5Z,8Z,11Z,14Z)/20:4(5Z,8Z,11Z,14Z)) (CAS 474943-33-4) is a high-purity analytical reference standard with the molecular formula C43H68O8PNa and a molecular weight of 766.97 g/mol.

Based on its molecular formula C43H68O8PNa, 1,2-di-(5Z,8Z,11Z,14Z-eicosatetraenoyl)-sn-glycero-3-phosphate (sodium salt) 1,2-diarachidonoyl-sn-glycero-3-phosphate (sodium salt) 20:4 PA 474943-33-4 DAPA PA(20:4(5Z,8Z,11Z,14Z)/20:4(5Z,8Z,11Z,14Z)) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 766.97 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
