Description

(1R)-(+)-trans-Isolimonene CAS NO 5113-87-1 is a high-purity, optically active monoterpene isomer, specifically the (1R,4R)-enantiomer of limonene. This compound is valued for its distinct stereochemistry and chiral purity, which are critical for applications in asymmetric synthesis and the production of high-value flavor and fragrance ingredients. It serves as a key chiral intermediate and building block for manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries.

Application

• Chiral Intermediate in Pharmaceutical Synthesis: Used as a starting material or building block for the synthesis of active pharmaceutical ingredients (APIs) requiring specific stereochemistry.
• Flavor and Fragrance (F&F) Industry: Imparts unique, refined citrus notes and is used in the formulation of premium perfumes, cosmetics, and food flavorings.
• Agrochemical Synthesis: Serves as a precursor in the development of chiral pesticides and herbicides, where the specific enantiomer can affect biological activity.
• Specialty Chemicals and Fine Chemicals: Employed in research and production of catalysts, ligands, and other high-value chemical products.
• Solvent for Specialty Applications: Can be used as a biodegradable and renewable solvent in niche applications requiring a specific terpene profile.
