Chemical Structure

Stearoyl L-alpha-Lysolecithin CAS 19420-57-6 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 Stearoyl L-alpha-Lysolecithin.

CATO supplies Stearoyl L-alpha-Lysolecithin (CAS 19420-57-6), a certified reference material (molecular formula C26H54NO7P, MW 523.68 g/mol) for analytical method development and quality control.

Owing to an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, Stearoyl L-alpha-Lysolecithin is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 523.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures Stearoyl L-alpha-Lysolecithin under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
