Description

Structurally, 1-octadecanoyl-2-(4Z,7Z,10Z,13Z,16Z,19Z-docosahexaenoyl)-sn-glycero-3-phosphate (sodium salt) 1-stearoyl-2-docosahexaenoyl-sn-glycero-3-phosphate (sodium salt) 18:0-22:6 PA 474943-30-1 PA(18:0/22:6(4Z,7Z,10Z,13Z,16Z,19Z)) (C43H72O8PNa) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 771.00 g/mol, it falls into the high-molecular-weight range. 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).

1-octadecanoyl-2-(4Z,7Z,10Z,13Z,16Z,19Z-docosahexaenoyl)-sn-glycero-3-phosphate (sodium salt) 1-stearoyl-2-docosahexaenoyl-sn-glycero-3-phosphate (sodium salt) 18:0-22:6 PA 474943-30-1 PA(18:0/22:6(4Z,7Z,10Z,13Z,16Z,19Z)) (CAS 474943-30-1), molecular formula C43H72O8PNa and molecular weight 771.00 g/mol, is a CATO reference standard with documented purity and traceability.

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.
