Description

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.

CATO supplies 1-octadecanoyl-2-(4Z,7Z,10Z,13Z,16Z,19Z-docosahexaenoyl)-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 1-stearoyl-2-docosahexaenoyl-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 18:0-22:6 PG 474943-27-6 PG(18:0/22:6(4Z,7Z,10Z,13Z,16Z,19Z)) (CAS 474943-27-6), a certified reference material (molecular formula C46H78O10PNa, MW 845.08 g/mol) for analytical method development and quality control.

The molecular framework of 1-octadecanoyl-2-(4Z,7Z,10Z,13Z,16Z,19Z-docosahexaenoyl)-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 1-stearoyl-2-docosahexaenoyl-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 18:0-22:6 PG 474943-27-6 PG(18:0/22:6(4Z,7Z,10Z,13Z,16Z,19Z)) (C46H78O10PNa) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
