Chemical Structure

1,2-di-(9Z,12Z-octadecadienoyl)-sn-glycero-3-phospho-L-serine (sodium salt) 1,2-dilinoleoyl-sn-glycero-3-phospho-L-serine (sodium salt) 18:2 PS 321883-39-0 PS(18:2(9Z,12Z)/18:2(9Z,12Z)) CAS 321883-39-0 chemical structure

Description

Based on its molecular formula C42H73NO10PNa, 1,2-di-(9Z,12Z-octadecadienoyl)-sn-glycero-3-phospho-L-serine (sodium salt) 1,2-dilinoleoyl-sn-glycero-3-phospho-L-serine (sodium salt) 18:2 PS 321883-39-0 PS(18:2(9Z,12Z)/18:2(9Z,12Z)) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 806.01 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies 1,2-di-(9Z,12Z-octadecadienoyl)-sn-glycero-3-phospho-L-serine (sodium salt) 1,2-dilinoleoyl-sn-glycero-3-phospho-L-serine (sodium salt) 18:2 PS 321883-39-0 PS(18:2(9Z,12Z)/18:2(9Z,12Z)) (CAS 321883-39-0), a certified reference material (molecular formula C42H73NO10PNa, MW 806.01 g/mol) for analytical method development and quality control.

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.
