CATO supplies All-rac-alfa-Tocopherol EP Impurity D (CAS CATO-C4X-119528), a pharmacopoeial impurity reference standard (molecular formula C40H76, MW 557.03 g/mol) used for the identification and quantification of trace impurities in APIs.
All-rac-alfa-Tocopherol EP Impurity D (C40H76) contains an organic framework. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
