Description

All-trans-Ethyl-β-Ionylideacetate is a high-purity, synthetic fragrance and flavor intermediate. This compound is valued for its role as a key building block in the synthesis of carotenoids and vitamin A derivatives, offering consistent quality and reliable performance. It is primarily sought after by manufacturers in the flavor and fragrance, cosmetic, and fine chemical synthesis industries for creating sophisticated aroma profiles and active ingredients.

Application

• Flavor & Fragrance Industry: A crucial intermediate for synthesizing ionones, damascones, and other high-value aroma chemicals used in perfumes, cosmetics, and personal care products.
• Vitamin A Synthesis: Serves as a key precursor in the industrial synthesis of Vitamin A (retinol) and its related compounds for nutritional and pharmaceutical applications.
• Carotenoid Production: Used in the manufacture of carotenoid pigments like β-carotene, which are applied as colorants and antioxidants in food, feed, and supplements.
• Fine Chemical Synthesis: Employed as a versatile chiral building block in organic synthesis for pharmaceuticals and agrochemicals.
• Cosmetic Actives: Incorporated into formulations for skincare products due to its structural relationship to retinoids, which are known for their beneficial effects on skin.
