1-octadecanoyl-2-(9Z,12Z-octadecadienoyl)-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 1-stearoyl-2-linoleoyl-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 18:0-18:2 PG 474943-26-5 PG(18:0/18:2(9Z,12Z)) (CAS 474943-26-5) is a high-purity analytical reference standard with the molecular formula C42H78O10PNa and a molecular weight of 797.04 g/mol.

Structurally, 1-octadecanoyl-2-(9Z,12Z-octadecadienoyl)-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 1-stearoyl-2-linoleoyl-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 18:0-18:2 PG 474943-26-5 PG(18:0/18:2(9Z,12Z)) (C42H78O10PNa) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 797.04 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
