Chemical Structure
Description
12:0 SM (d18:1/12:0) 474923-21-2 Dodecanoyl Sphingomyelin N-(dodecanoyl)-sphing-4-enine-1-phosphocholine N-lauroyl-D-erythro-sphingosylphosphorylcholine (C35H71N2O6P) contains an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
