(Rp)-(1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl (3-hydroxynaphthalen-2-yl)(phenyl)phosphinate CAS 1592980-26-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (Rp)-(1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl (3-hydroxynaphthalen-2-yl)(phenyl)phosphinate.

(Rp)-(1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl (3-hydroxynaphthalen-2-yl)(phenyl)phosphinate (CAS 1592980-26-1) is a high-purity analytical reference standard with the molecular formula C26H31O3P and a molecular weight of 422.50 g/mol.

Based on its molecular formula C26H31O3P, (Rp)-(1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl (3-hydroxynaphthalen-2-yl)(phenyl)phosphinate contains a steroid core, a phosphonate group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 422.50 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.
