Chemical Structure
Description
Based on its molecular formula C6H10NO6PNaH2O, 333338-18-4 Phosphoric acid, mono(4-nitrophenyl) ester, sodium salt, hydrate(1:2:6)OTHER CA INDEX NAMES:Phosphoric acid, mono(4-nitrophenyl) ester, disodium salt, hexahydrate contains a carbohydrate-derived structure, an amide group, a phosphate ester group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 264.13 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.
333338-18-4 Phosphoric acid, mono(4-nitrophenyl) ester, sodium salt, hydrate(1:2:6)OTHER CA INDEX NAMES:Phosphoric acid, mono(4-nitrophenyl) ester, disodium salt, hexahydrate (CAS 333338-18-4) is a high-purity analytical reference standard with the molecular formula C6H10NO6PNaH2O and a molecular weight of 264.13 g/mol.
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.
