Description

2-Methyl-3-(3,7,11,15-Tetramethylhexadec-2-Enyl)-1,4-Naphthoquinone is a high-purity synthetic form of Vitamin K2, specifically the menaquinone-4 (MK-4) isomer, which is critical for its role in calcium metabolism and bone health. This compound is essential for manufacturers requiring a reliable and consistent raw material for advanced nutraceutical, pharmaceutical, and research applications. It is primarily sought by producers of dietary supplements, bone health formulations, and specialized clinical nutrition products, where precise biological activity and stringent quality are paramount.

Application

• Nutraceutical & Dietary Supplements: As the active ingredient in high-potency Vitamin K2 (MK-4) capsules, tablets, and softgels for supporting cardiovascular and bone health.
• Pharmaceutical Intermediates: Used in the synthesis of specialized pharmaceutical agents targeting osteoporosis and vascular calcification.
• Clinical Nutrition: Formulated into medical foods and parenteral nutrition solutions for patients with specific metabolic deficiencies.
• Research & Development: Serves as a critical reference standard and biochemical reagent in metabolic, bone, and cardiovascular research studies.
• Functional Food & Beverage Fortification: Incorporated into health-focused food products like dairy alternatives, sports nutrition bars, and fortified beverages.
• Cosmeceuticals: Utilized in topical skincare formulations for its purported benefits in skin health and elasticity.

Quality Control

Our 2-Methyl-3-(3,7,11,15-Tetramethylhexadec-2-Enyl)-1,4-Naphthoquinone is manufactured under strict quality systems. Each batch is tested to ensure it meets high-purity standards suitable for nutraceutical and research applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term stability, especially after opening the primary container. Keep away from heat and incompatible materials.
