Chemical Structure

1-Stearoyl-sn-lysophosphatidylethanolamin CAS 69747-55-3 chemical structure

Description

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.

1-Stearoyl-sn-lysophosphatidylethanolamin (CAS 69747-55-3) is a high-purity analytical reference standard with the molecular formula C23H48NO7P and a molecular weight of 481.60 g/mol.

The molecular framework of 1-Stearoyl-sn-lysophosphatidylethanolamin (C23H48NO7P) 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.

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.
