CATO supplies (3aR,3′aR,8aS,8′aS)-2,2′-(1-Methyl-2-phenylethylidene)bis[3a,8a-dihydro-8H-indeno[1,2-d]oxazole] (CAS 2757082-37-2), a certified reference material (molecular formula C29H26N2O2, MW 434.53 g/mol) for analytical method development and quality control.
(3aR,3′aR,8aS,8′aS)-2,2′-(1-Methyl-2-phenylethylidene)bis[3a,8a-dihydro-8H-indeno[1,2-d]oxazole] (C29H26N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
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.
