(±)-α-Tocopherol (Vitamin E) is a fat-soluble antioxidant commonly analyzed in clinical, nutraceutical, food, and pharmaceutical testing. This certified reference material (CRM) solution is prepared at a concentration of 1.0 mg/mL in methanol and supplied in a flame-sealed 1 mL ampule under inert gas to preserve stability and prevent oxidation.

The material is fully characterized under ISO/IEC 17025 and ISO 17034 accreditation and is accompanied by a comprehensive Certificate of Analysis (CoA) documenting concentration accuracy, uncertainty, homogeneity, stability, and traceability.

This single-component CRM is suitable for use as a calibration standard, spiking solution, or quality control material for chromatographic determination of vitamin E in a variety of matrices, including serum, plasma, edible oils, dietary supplements, and pharmaceutical preparations. It is compatible with gas chromatography (GC) and liquid chromatography (LC) techniques, including HPLC and LC-MS/MS.

Typical laboratory applications include quantitative determination of vitamin E in biological samples, nutritional studies, quality control testing of tocopherol-containing products, and method validation for food and supplement analysis.

This certified reference material is supplied with a certificate of analysis providing traceable concentration values suitable for calibration, method validation, and analytical quality control.

Shipping and Storage Notice
Please note that shipping and long-term storage conditions for certified reference materials may differ. Manufacturers determine the most appropriate shipping method based on product stability and shipping data. Some CRM standards may ship at ambient temperature even though recommended long-term storage conditions are refrigerated or frozen. This does not affect product integrity when handled according to manufacturer documentation.
