Description

.Beta.,.Epsilon.-Carotene-3,3-Diol, Ditetradecanoate, (3R,3R,6R)- is a high-purity, esterified carotenoid derivative, specifically a diester of zeaxanthin, valued for its enhanced stability and lipophilic properties compared to its parent compound. This compound is critical for applications requiring a stable, oil-soluble source of xanthophyll activity or specific stereochemical configuration. It serves as a key advanced intermediate or reference standard for manufacturers in the nutraceutical, pharmaceutical, and high-value specialty chemical sectors.

Application

• Nutraceutical Ingredient: Used in the formulation of advanced eye health and antioxidant dietary supplements, leveraging its role as a stabilized zeaxanthin derivative.
• Pharmaceutical Research: Serves as a critical reference standard or building block in R&D for drugs targeting oxidative stress and age-related macular degeneration (AMD).
• Food & Beverage Fortification: Employed as a colorant and functional nutrient in premium fortified foods and beverages where oil solubility is required.
• Cosmetic & Personal Care: Incorporated into skincare formulations for its antioxidant properties, helping to protect skin from environmental damage.
• Analytical & Bioassay Standards: Provides a certified standard for quality control and analytical testing in laboratories.
• Animal Nutrition: Used in specialty feed for aquaculture and poultry to enhance pigmentation and animal health.
