Chemical Structure
Description
(S)-4-((Diphenylphosphino)methyl)-2-(pyridin-2-yl)-4,5-dihydrooxazole (C21H19N2OP) contains a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
(S)-4-((Diphenylphosphino)methyl)-2-(pyridin-2-yl)-4,5-dihydrooxazole (CAS 679788-24-0) is a high-purity analytical reference standard with the molecular formula C21H19N2OP and a molecular weight of 346.36 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.
