Description

(E)-Limoneneoxide,trans-1,2-Epoxy-p-Menth-8-Ene,trans-Limoneneepoxide,(E)-Limoneneoxide CAS NO 4959-35-7 is a high-purity, monoterpene epoxide derived from limonene, valued for its specific stereochemistry and functional epoxide group. This compound is a versatile chiral intermediate and building block in organic synthesis, enabling the production of fine chemicals and specialty materials. It is primarily sought by manufacturers in the flavor & fragrance, pharmaceutical, and agrochemical industries for its role in creating complex, high-value molecules.

Application

• Flavor and Fragrance Synthesis: A key chiral intermediate for creating terpene-based aroma chemicals, imparting fresh, citrus, or woody notes.
• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) and other bioactive compounds due to its reactive epoxide moiety.
• Agrochemical Production: Serves as a building block for certain pesticides, herbicides, and plant growth regulators.
• Fine Chemical Manufacturing: Employed in asymmetric synthesis and catalysis research to develop novel chemical entities.
• Polymer and Resin Modifiers: Can be used as a reactive diluent or cross-linking agent in specialty epoxy resin formulations.
• Academic and R&D: A valuable reagent for organic chemistry research, particularly in studies involving terpene chemistry and epoxide ring-opening reactions.
