Chemical Structure

1-o-octadecyl-2-hydroxy-sn-glycero-3-phosphate ammonium salt 799279-67-7 CAS 799279-67-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 441.59 g/mol gives 1-o-octadecyl-2-hydroxy-sn-glycero-3-phosphate ammonium salt 799279-67-7 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-o-octadecyl-2-hydroxy-sn-glycero-3-phosphate ammonium salt 799279-67-7 (CAS 799279-67-7) is a high-purity analytical reference standard with the molecular formula C21H44O6PH4N and a molecular weight of 441.59 g/mol.

The molecular framework of 1-o-octadecyl-2-hydroxy-sn-glycero-3-phosphate ammonium salt 799279-67-7 (C21H44O6PH4N) is characterized by an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
