(Sp)-(1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl (2,5-dihydroxy-3,6-dimethylphenyl)(phenyl)phosphinate (C24H33O4P) contains a flavonoid core, a phosphate ester group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
(Sp)-(1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl (2,5-dihydroxy-3,6-dimethylphenyl)(phenyl)phosphinate (CAS 1420992-11-5) is a high-purity analytical reference standard with the molecular formula C24H33O4P and a molecular weight of 416.49 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.
