88928BS57E 221139-79-3 EC-18 UNII-88928BS57E 1-Palmitoyl-2-linoleoyl-3-acetyl-rac-glycerol 9,12-Octadecadienoic acid (9Z,12Z)-, 1-((acetyloxy)methyl)-2-((1-oxohexadecyl)oxy)ethyl ester Plag, (+/-) Mosedipimod [USAN] Mosedipimod WHO 10702 1-palmitoyl-2-linoleoyl-3-acetyl-rac glycerol EC-18 cpd PLA-racglycerol (CAS 221139-79-3), molecular formula C39H70O6 and molecular weight 634.97 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 88928BS57E 221139-79-3 EC-18 UNII-88928BS57E 1-Palmitoyl-2-linoleoyl-3-acetyl-rac-glycerol 9,12-Octadecadienoic acid (9Z,12Z)-, 1-((acetyloxy)methyl)-2-((1-oxohexadecyl)oxy)ethyl ester Plag, (+/-) Mosedipimod [USAN] Mosedipimod WHO 10702 1-palmitoyl-2-linoleoyl-3-acetyl-rac glycerol EC-18 cpd PLA-racglycerol (C39H70O6) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 634.97 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
