Description

4'-Apo-β,ψ-Caroten-4'-Oic Acid is a specialized carotenoid derivative, a key intermediate in the synthesis of higher-value apocarotenoids. This compound matters for its role as a versatile building block in the production of fine chemicals, nutritional ingredients, and research standards. It is primarily needed by manufacturers and R&D teams in the nutraceutical, pharmaceutical, and specialty chemical industries seeking high-purity intermediates for synthesis and analysis.

Application

• Nutraceutical Ingredient Synthesis: A crucial intermediate in the production of apocarotenoids like apo-8'-carotenal and apo-12'-carotenal, which are used as colorants and provitamin A sources.
• Pharmaceutical Research: Serves as a reference standard and a key starting material for the development of retinoid-like compounds with potential biological activity.
• Food & Beverage Colorants: Used in the manufacturing chain for natural color additives approved for food use (e.g., E 160e).
• Animal Feed Additives: A precursor in the synthesis of carotenoids used to enhance the coloration and nutritional value of feed for poultry and aquaculture.
• Cosmetic & Personal Care: Employed in the synthesis of pigments and antioxidants for skincare and cosmetic formulations.
• Analytical & Diagnostic Reagents: Used as a high-purity standard in HPLC and LC-MS methods for quality control and research in related product streams.
