Description

Butyl 3-Hydroxy-3-Methyl-5-(2,6,6-Trimethyl-2-Cyclohexen-1-Yl)Pent-4-En-1-Oate is a high-purity synthetic intermediate characterized by its complex terpenoid-like structure. This compound matters for its role as a versatile building block in the synthesis of fine chemicals and active pharmaceutical ingredients (APIs), offering a defined chiral center and functional groups for further chemical elaboration. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, fragrance, and specialty chemical industries seeking to develop novel compounds with specific stereochemistry.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the research and development of novel therapeutic agents, particularly in steroid-like or terpenoid-based drug candidates.
• Fragrance & Flavor Synthesis: Serves as a precursor for creating complex, natural-identical aroma molecules and flavor compounds due to its structural similarity to ionone and related terpenoids.
• Fine Chemical Production: Used in organic synthesis for constructing complex molecular architectures requiring specific hydroxyl and ester functionalities.
• Academic & Industrial Research: A valuable reference standard and starting material for chemical research exploring new synthetic methodologies and catalysis.
• Cosmetic Ingredient Synthesis: Potential intermediate in the production of specialty esters and derivatives used in high-end cosmetic formulations.
