(R)-(-)-(3,5-Dioxa-4-phosphacyclohepta[2,1-a;3,4-a] dinaphthalen-4-yl)dimethylamine CAS 157488-65-8 chemical structure

Description

The occurrence of (R)-(-)-(3,5-Dioxa-4-phosphacyclohepta[2,1-a;3,4-a] dinaphthalen-4-yl)dimethylamine is closely related to a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(R)-(-)-(3,5-Dioxa-4-phosphacyclohepta[2,1-a;3,4-a] dinaphthalen-4-yl)dimethylamine (CAS 157488-65-8) is a high-purity analytical reference standard with the molecular formula C22H18NO2P and a molecular weight of 359.36 g/mol.

Based on its molecular formula C22H18NO2P, (R)-(-)-(3,5-Dioxa-4-phosphacyclohepta[2,1-a;3,4-a] dinaphthalen-4-yl)dimethylamine contains a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 359.36 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.

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.
