18:1 EPC (Cl Salt)

1,2-dioleoyl-sn-glycero-3-ethylphosphocholine (chloride salt)

O-alkyl phosphatidylcholines constitute the first chemically stable triesters of biological lipid structures and the first cationic derivatives of phospholipids consisting entirely of biological metabolites linked with ester bonds. The lipid has low toxicity and is biodegradable.
