Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-2,3-Bis(stearoyloxy)propyl (2-(trimethylammonio)ethyl) phosphate.
(S)-2,3-Bis(stearoyloxy)propyl (2-(trimethylammonio)ethyl) phosphate (CAS 66701-63-1), molecular formula C44H88NO8P and molecular weight 790.15 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (S)-2,3-Bis(stearoyloxy)propyl (2-(trimethylammonio)ethyl) phosphate (C44H88NO8P) is characterized by an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
