Chemical Structure

DL-b,g-Distearoyl-a-lecithin CAS 4539-70-2 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 DL-b,g-Distearoyl-a-lecithin.

CATO supplies DL-b,g-Distearoyl-a-lecithin (CAS 4539-70-2), a certified reference material (molecular formula C44H88NO8P, MW 790.15 g/mol) for analytical method development and quality control.

DL-b,g-Distearoyl-a-lecithin (C44H88NO8P) 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.

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.
