PtdIns-（1-arachidonoyl， 2-arachidonoyl-d8） is used as an internal standard for the quantification of PtdIns-（1-arachidonoyl， 2-arachidonoyl） by stable isotope dilution MS. The accuracy of the sample weight in this vial is between 5% over and 2% under the amount shown on the vial. If better precision is required， the deuterated standard should be quantitated against a more precisely weighed unlabeled standard by constructing a standard curve of peak intensity ratios （deuterated versus unlabeled）. The phosphatidylinositols （PtdIns） represent a small percentage of total membrane phospholipids. However， they play a critical role in the generation and transmission of cellular signals. PtdIns-（1-arachidonoyl， 2-arachidonoyl-d8） （sodium salt） is a synthetic analog of natural PtdIns featuring deuterated C20:4 fatty acids at the sn-2 position. This synthetic standard compound contains the same inositol and diacyl glycerol （DAG） stereochemistry as that of the natural compound.
