1-stearoyl-2-palmitoyl-sn-glycero-3-phosphocholine CAS 59403-53-1

Description

The occurrence of 1-stearoyl-2-palmitoyl-sn-glycero-3-phosphocholine is closely related to an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-stearoyl-2-palmitoyl-sn-glycero-3-phosphocholine (CAS 59403-53-1), molecular formula C42H84NO8P and molecular weight 762.09 g/mol, is a CATO reference standard with documented purity and traceability.

1-stearoyl-2-palmitoyl-sn-glycero-3-phosphocholine (C42H84NO8P) 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.
