Description

Methylbetaapo8Carotenate is a synthetic carotenoid derivative, specifically the methyl ester of β-apo-8'-carotenoid acid. This compound is valued for its intense colorant properties and its role as a key intermediate in the synthesis of other carotenoids and fine chemicals. It is primarily utilized by manufacturers in the food, feed, and nutraceutical industries seeking reliable, high-purity color additives and precursors.

Application

• As a colorant and pigment precursor in the production of food and beverage products.
• As a feed additive to enhance the coloration of poultry skin and egg yolks.
• As a key intermediate in pharmaceutical synthesis for vitamin A and related retinoids.
• In the manufacture of cosmetic and personal care products requiring stable, natural-color pigments.
• As a reference standard in analytical and quality control laboratories.
• For research and development in nutritional science and carotenoid chemistry.

Quality Control

Our Methylbetaapo8Carotenate is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide full traceability and Certificates of Analysis (COA) are available for all commercial shipments, detailing key parameters such as assay, related substances, and heavy metal content.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen or argon) is recommended to preserve stability and color potency.
