Chemical Structure
Description
Structurally, 2-Chloro-4-nitrophenyl dihydrogen phosphate (C6H5ClNO6P) contains a carbohydrate-derived structure, an amide group, a phosphate ester group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 253.53 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
2-Chloro-4-nitrophenyl dihydrogen phosphate (CAS 14957-98-3) is a high-purity analytical reference standard with the molecular formula C6H5ClNO6P and a molecular weight of 253.53 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.
