Description

The occurrence of 1,2-di-(9Z,12Z-octadecadienoyl)-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 1,2-dilinoleoyl-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 18:2 PG 322729-38-4 PG(18:2(9Z,12Z)/18:2(9Z,12Z)) is closely related to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1,2-di-(9Z,12Z-octadecadienoyl)-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 1,2-dilinoleoyl-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 18:2 PG 322729-38-4 PG(18:2(9Z,12Z)/18:2(9Z,12Z)) (CAS 322729-38-4), a certified reference material (molecular formula C42H74O10PNa, MW 793.01 g/mol) for analytical method development and quality control.

1,2-di-(9Z,12Z-octadecadienoyl)-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 1,2-dilinoleoyl-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 18:2 PG 322729-38-4 PG(18:2(9Z,12Z)/18:2(9Z,12Z)) (C42H74O10PNa) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), 1,2-di-(9Z,12Z-octadecadienoyl)-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 1,2-dilinoleoyl-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 18:2 PG 322729-38-4 PG(18:2(9Z,12Z)/18:2(9Z,12Z)) meets the metrological traceability requirements of ISO/IEC 17025 laboratories.
