Description

Hexanoic Acid, 3-Hydroxy-, Ethyl Ester, (3R)- is a chiral ester derivative of 3-hydroxyhexanoic acid, a compound of significant interest in fine chemical synthesis. This optically pure (R)-enantiomer is valued for its role as a key chiral building block and flavor/fragrance intermediate. It is primarily sought by manufacturers in the pharmaceutical, flavor & fragrance, and advanced material sectors for the production of high-value specialty chemicals.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs), particularly in routes requiring the (R)-3-hydroxyhexanoate moiety.
• Flavor & Fragrance Ingredient: Used in the creation of complex, fruity, or creamy flavor profiles and as a component in sophisticated fragrance compositions.
• Chemical Research & Development: Serves as a standard or starting material in asymmetric synthesis and catalysis studies within academic and industrial R&D laboratories.
• Polymer & Material Science: A potential monomer or co-monomer for the synthesis of specialized biodegradable polyesters with tailored properties.
• Agrochemical Synthesis: An intermediate in the production of certain chiral agrochemicals, such as pheromones or selective pesticides.
