Diethyl (((2-amino-4-chlorophenyl)amino)methyl)phosphonate hydrochloride CAS 301822-79-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Diethyl (((2-amino-4-chlorophenyl)amino)methyl)phosphonate hydrochloride.

Diethyl (((2-amino-4-chlorophenyl)amino)methyl)phosphonate hydrochloride (CAS 301822-79-7), molecular formula C11H18ClN2O3PHCl and molecular weight 329.16 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H18ClN2O3PHCl, Diethyl (((2-amino-4-chlorophenyl)amino)methyl)phosphonate hydrochloride contains an amide group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 329.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
