Description

2-Hydroxymethyl-2,5,7,8-Tetramethylchroman-6-Ol is a high-purity synthetic antioxidant belonging to the chromanol family, a key structural motif in Vitamin E analogs. This compound matters for its potent ability to inhibit oxidative degradation, thereby extending the shelf life and stability of sensitive formulations. It is primarily needed by manufacturers in the pharmaceutical, nutraceutical, and high-performance polymer industries seeking advanced stabilization solutions.

Application

• Pharmaceutical Intermediates: As a key building block in the synthesis of tocopherol (Vitamin E) derivatives and other chroman-based active pharmaceutical ingredients (APIs).
• Nutraceutical & Cosmetic Antioxidants: Incorporated into dietary supplements, functional foods, and personal care products to protect active ingredients from oxidation.
• Polymer & Plastic Stabilization: Used as an additive to prevent the oxidative degradation of polymers, plastics, and synthetic rubbers during processing and service life.
• Research & Development: Serves as a reference standard and a crucial reagent in biochemical and pharmacological research focused on antioxidant mechanisms.
• Lubricant & Fuel Additives: Enhances the oxidative stability of industrial lubricants and specialty fuels.

Quality Control

Our 2-Hydroxymethyl-2,5,7,8-Tetramethylchroman-6-Ol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets stringent specifications. Certificates of Analysis (COA) are provided with every shipment, and we support compliance with cGMP, ISO, and other relevant regulatory frameworks for pharmaceutical and industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption and degradation.
