19805-18-6 1,2-Dielaidoyl-sn-glycero-3-phosphorylethanolamine 1,2-Dielaidyl-sn-glycero-3-phosphorylethanolamine DEPE L-alpha-Dielaidoylphosphatidylethanolamine (CAS 19805-18-6) is a high-purity analytical reference standard with the molecular formula C41H78NO8P and a molecular weight of 744.03 g/mol.
19805-18-6 1,2-Dielaidoyl-sn-glycero-3-phosphorylethanolamine 1,2-Dielaidyl-sn-glycero-3-phosphorylethanolamine DEPE L-alpha-Dielaidoylphosphatidylethanolamine (C41H78NO8P) contains an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
