Description

[1S-(1Alpha,3Abeta,4Alpha,8Abeta,9S*)]-Decahydro-4,8,8-Trimethyl-1,4-Methanoazulene-9-Carboxaldehyde CAS NO 66537-42-6 is a high-purity, stereochemically defined sesquiterpene derivative. This compound serves as a critical chiral intermediate and building block in advanced organic synthesis, valued for its complex, rigid molecular framework. It is primarily sought by R&D and production teams in the pharmaceutical, fragrance, and fine chemical industries for developing novel active ingredients and specialty aroma chemicals.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the research and development of novel therapeutic agents, particularly in steroid and terpenoid-based drug discovery.
• Fragrance & Flavor Synthesis: Used as a precursor for creating unique, complex woody, ambery, or musky odorants in high-end perfumery and flavor compositions.
• Organic Synthesis Building Block: Employed in asymmetric synthesis and total synthesis projects due to its defined stereocenters and methanoazulene backbone.
• Agrochemical Research: Potential intermediate in the development of new bioactive compounds for crop protection.
• Material Science Research: Investigated as a monomer or precursor for specialty polymers with specific optical or structural properties.
• Reference Standard: Serves as an analytical standard for quality control and research in laboratories.
