Chemical Structure
Description
1,2-Distearoyl-rac-glycero-3-phosphocholine 2,3-bis(stearoyloxy)propyl 2-(trimethylammonio)ethyl phosphate 816-93-3 (CAS 816-93-3) is a high-purity analytical reference standard with the molecular formula C44H89NO8P and a molecular weight of 791.15 g/mol.
1,2-Distearoyl-rac-glycero-3-phosphocholine 2,3-bis(stearoyloxy)propyl 2-(trimethylammonio)ethyl phosphate 816-93-3 (C44H89NO8P) 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
