Special InstructionsNote: most vials contain 50 mg tocopherol ± 10%, although some may contain more. If the material is to be used as a quantitative standard, it is recommended that the material be weighed analytically before use. If small quantities of tocopherol are to be used at one time, slowly draw the material from the vial using a Hamilton syringe, flush with inert gas, and re-seal the vial. If the entire vial is to be used at once, use the following procedure to determine the exact amount of material in each vial:

1. Measure the weight of the vial with tocopherol.
2. Use an organic solvent (e.g. Ethanol) to make a solution of the entire contents of the vial.
3. Dry the vial and measure the weight of the dry vial. **Note: the solvent must be completely evaporated from the sample before use.**
4. Calculate the mass of the tocopherol that was in the original solution based on the following information:
all-rac-α-tocopherol, C₂₉H₅₀O₂, MW 430.7
all-rac-β-tocopherol, C₂₈H₄₈O₂, MW 416.7
RRR-γ-tocopherol, C₂₈H₄₈O₂, MW 416.7
RRR-δ-tocopherol, C₂₇H₄₆O₂, MW 402.7
