Cholecalciferol EP Impurity F (Cholecalciferol Butyrate) (CAS 31316-20-8) is a certified pharmaceutical impurity reference standard with the molecular formula C31H50O2 and a molecular weight of 454.73 g/mol.
Cholecalciferol EP Impurity F (Cholecalciferol Butyrate) (C31H50O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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 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).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
