Chemical Structure
Description
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.
Diphenyl (1-amino-2-phenylethyl)phosphonate hydrochloride (CAS 1171995-49-5) is a high-purity analytical reference standard with the molecular formula C20H20NO3PHCl and a molecular weight of 389.82 g/mol.
Based on its molecular formula C20H20NO3PHCl, Diphenyl (1-amino-2-phenylethyl)phosphonate hydrochloride contains a steroid core, an amide group, a phosphonate group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 389.82 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
