Sigma-Aldrich® Tocopherol Set (Vial Pack Containing ~50 Mg Each Of All-Rac-Α, All-Rac-Β, Rrr-Γ, And Rrr-Δ-Tocopherols), ≥95% For Each Component, Hplc

The Calbiochem® Tocopherol Set is a convenient, high-purity multi-component reference standard kit designed for the quantitative and qualitative determination of vitamin E (tocopherols) in biological, food, and research samples. This comprehensive kit contains four individual vials, each supplied with approximately 50 mg of a specific tocopherol isomer: all-rac-α-tocopherol, all-rac-β-tocopherol, RRR-γ-tocopherol, and RRR-δ-tocopherol.

Vitamin E is a collective term encompassing several structurally related tocopherols and tocotrienols, with α-tocopherol exhibiting the highest biological activity. Analytical studies in clinical and nutritional research commonly rely on plasma or serum α-tocopherol levels to assess vitamin E status. Beyond its well-established antioxidant role in preventing lipid peroxidation, vitamin E has been shown to possess anti-tumor, cardioprotective, and cell signaling functions, contributing to its broad relevance in biomedical research.

Manufactured by Calbiochem® (Merck) and packaged under inert gas to ensure stability, this tocopherol set provides ≥95% purity (HPLC) for each component, ensuring accuracy, reproducibility, and traceability in advanced analytical workflows.

Handling & Preparation Notes

For quantitative use, it is recommended to analytically weigh the contents of each vial prior to use, as vial content may vary by ±10%. When withdrawing small volumes, use a Hamilton syringe, flush with inert gas, and reseal promptly. If using the entire vial, dissolve the contents in a suitable organic solvent (e.g. ethanol) and determine the exact mass gravimetrically.

The Calbiochem® Tocopherol Set offers a robust, high-quality reference standard solution for vitamin E analysis, supporting reliable research outcomes across clinical, nutritional, food safety, and biochemical applications. Its comprehensive isomer coverage and analytical-grade purity make it an essential tool for laboratories performing advanced tocopherol profiling.
