Chemical Structure
Description
The occurrence of 1-hexadecanoyl-2--(5Z,8Z,11Z,14Z-eicosatetraenoyl)-sn-glycero-3-phosphate (sodium salt) 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphate (sodium salt) 16:0-20:4 PA 322647-60-9 PA(16:0/20:4(5Z,8Z,11Z,14Z)) PAPA is closely related to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-hexadecanoyl-2--(5Z,8Z,11Z,14Z-eicosatetraenoyl)-sn-glycero-3-phosphate (sodium salt) 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphate (sodium salt) 16:0-20:4 PA 322647-60-9 PA(16:0/20:4(5Z,8Z,11Z,14Z)) PAPA (CAS 322647-60-9), molecular formula C39H68O8PNa and molecular weight 718.93 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-hexadecanoyl-2--(5Z,8Z,11Z,14Z-eicosatetraenoyl)-sn-glycero-3-phosphate (sodium salt) 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphate (sodium salt) 16:0-20:4 PA 322647-60-9 PA(16:0/20:4(5Z,8Z,11Z,14Z)) PAPA (C39H68O8PNa) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
