Description

2-Methyl-3-(3,7,11,15,19,23,27-Heptamethyl-2,6,10,14,18,22,26-Octacosaheptenyl)-1,4-Naphthoquinone is a high-purity synthetic form of Vitamin K2, specifically the menaquinone-7 (MK-7) isomer, which is critical for its superior bioavailability and biological activity. This compound is essential for applications requiring precise control over calcium metabolism and bone health. It is primarily sought by manufacturers in the nutraceutical, pharmaceutical, and advanced food fortification industries for producing high-end dietary supplements and functional foods.

Application

• Nutraceutical & Dietary Supplements: As the active ingredient in premium bone health, cardiovascular, and anti-aging formulations, particularly for its long half-life as MK-7.
• Pharmaceutical Intermediates: Used in the research and development of drugs targeting osteoporosis, vascular calcification, and other disorders related to vitamin K-dependent proteins.
• Functional Food & Beverage Fortification: Incorporated into dairy products, health drinks, and specialized nutritional products to enhance their vitamin K2 content.
• Cosmeceutical Research: Investigated for topical applications in skincare products aimed at improving skin elasticity and reducing signs of aging.
• Animal Nutrition: Used in premium feed additives for livestock and pets to support bone density and overall metabolic health.
• Biochemical Research: Serves as a critical standard and reagent in clinical studies and laboratory analysis of vitamin K metabolism.

Quality Control

Our 2-Methyl-3-(3,7,11,15,19,23,27-Heptamethyl-2,6,10,14,18,22,26-Octacosaheptenyl)-1,4-Naphthoquinone (MK-7) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity, correct isomeric form, and compliance with relevant standards for nutraceutical and research use. Certificates of Analysis (COA) documenting purity, assay, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) at 2-8°C to minimize oxidation and degradation. For long-term storage, keep the container in a freezer at -20°C. The material is light-sensitive and easily oxidized; allow the sealed container to reach room temperature before opening to prevent moisture condensation.
