Description

7,8-Dimethyltocol is a synthetic analog of vitamin E (tocopherol) with specific alkylation on the chromanol ring. This compound is valued for its potent antioxidant properties and serves as a crucial reference standard and research chemical in the study of lipid peroxidation and cellular protection mechanisms. It is primarily utilized by research institutions, pharmaceutical developers, and manufacturers in the nutraceutical and analytical chemistry sectors for method development, quality control, and biochemical research.

Application

• Pharmaceutical Reference Standard: Used as a high-purity certified reference material (CRM) for the identification and quantification of tocopherols and tocotrienols in drug formulations and raw materials via HPLC or GC analysis.
• Nutraceutical & Dietary Supplement Research: Employed in R&D to study the structure-activity relationship of vitamin E analogs, their bioavailability, and metabolic pathways.
• Antioxidant Mechanism Studies: A key reagent in biochemical and in-vitro research to investigate antioxidant efficacy, radical scavenging activity, and protection against oxidative stress in lipids and biological membranes.
• Analytical Chemistry: Serves as an internal standard or calibration compound in chromatographic methods for the analysis of vitamin E content in food, feed, and biological samples.
• Cosmetic Ingredient Research: Used in the development and testing of advanced skincare formulations for its potential stabilizing and protective effects against environmental oxidants.

Quality Control

Our 7,8-Dimethyltocol is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the stringent requirements for research and reference standard applications. Certificates of Analysis (COA) with detailed chromatographic data are provided to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at 2-8°C under an inert atmosphere (e.g., argon or nitrogen) to prevent oxidation. Keep the container in a cool, dry, and well-ventilated area, away from heat sources and incompatible materials.
