The occurrence of tert-Butyl-[3S-(2-(1R-[2-(diphenyl-phosphinoyl)-1S-methyl-ethyl]-7R-methyl-octahydro-inden-4-ylidene)-ethylidene)-4-methylene-cyclohexyloxy]-dimethyl-silane is closely related to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
tert-Butyl-[3S-(2-(1R-[2-(diphenyl-phosphinoyl)-1S-methyl-ethyl]-7R-methyl-octahydro-inden-4-ylidene)-ethylidene)-4-methylene-cyclohexyloxy]-dimethyl-silane (CAS 344798-27-2), molecular formula C40H57O2PSi and molecular weight 628.94 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C40H57O2PSi, tert-Butyl-[3S-(2-(1R-[2-(diphenyl-phosphinoyl)-1S-methyl-ethyl]-7R-methyl-octahydro-inden-4-ylidene)-ethylidene)-4-methylene-cyclohexyloxy]-dimethyl-silane contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 628.94 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
