Description

(3S)-3-Hydroxy-β-Ionone is a high-purity, optically active ketone derivative of β-ionone, valued for its role as a key chiral intermediate and flavor/fragrance precursor. This compound matters for its ability to impart specific sensory characteristics and its utility in the synthesis of more complex molecules like carotenoids and vitamins. It is needed by manufacturers in the flavor & fragrance, pharmaceutical, and nutraceutical industries seeking to develop premium products with precise stereochemistry and aroma profiles.

Application

• Flavor & Fragrance Ingredient: Used as a building block for synthesizing valuable aroma chemicals like damascones and ionones, contributing to fruity, floral, and woody notes in perfumes and food flavorings.
• Pharmaceutical Intermediate: Serves as a critical chiral synthon in the production of retinoids, carotenoids, and other bioactive compounds with vitamin A activity.
• Nutraceutical Synthesis: Employed in the research and development of advanced nutritional supplements, including specialized carotenoid derivatives.
• Cosmetic Actives: Utilized in the formulation of high-end skincare products for its potential as a precursor to compounds with beneficial properties for skin health.
• Chemical Research (R&D): Acts as a standard or starting material in organic synthesis and analytical method development for academic and industrial laboratories.
• Agrochemical Intermediates: Can be used in the synthesis of certain plant growth regulators or specialty agrochemicals.
