Hexadecanoic acid, 1,1'-[(1R)-1-(19-amino-3-hydroxy-3-oxido-8-oxo-2,4-dioxa-7-aza-3-phosphanonadec-1-yl)-1,2-ethanediyl] ester CAS 474944-08-6

Description

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.

CATO supplies Hexadecanoic acid, 1,1'-[(1R)-1-(19-amino-3-hydroxy-3-oxido-8-oxo-2,4-dioxa-7-aza-3-phosphanonadec-1-yl)-1,2-ethanediyl] ester (CAS 474944-08-6), a certified reference material (molecular formula C49H97N2O9P, MW 889.28 g/mol) for analytical method development and quality control.

Based on its molecular formula C49H97N2O9P, Hexadecanoic acid, 1,1'-[(1R)-1-(19-amino-3-hydroxy-3-oxido-8-oxo-2,4-dioxa-7-aza-3-phosphanonadec-1-yl)-1,2-ethanediyl] ester contains an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 889.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
