Description

3,3,5,6,7-Pentamethyl-1-Indanone CAS NO 16204-69-6 is a high-purity, multi-methylated indanone derivative that serves as a critical synthetic intermediate and building block in advanced organic chemistry. Its unique sterically hindered structure makes it valuable for creating complex molecules with specific functional properties. This compound is primarily sought by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty fragrance industries for the synthesis of novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly in medicinal chemistry research targeting complex heterocyclic structures.
• Agrochemical Synthesis: Used in the development of advanced pesticides and herbicides, where its methylated indanone core contributes to specific biological activity and stability.
• Fragrance & Flavor Chemistry: Serves as a precursor for musky or amber-type odorants and specialty aroma chemicals due to its polycyclic, methylated framework.
• Material Science Research: Acts as a monomer or precursor for organic electronic materials, such as ligands for metal-organic frameworks (MOFs) or components for organic semiconductors.
• Organic Synthesis & Catalysis: A valuable substrate in methodological studies for C-H activation, cross-coupling reactions, and the development of new catalytic processes.
• Chemical Reference Standard: Supplied as a high-purity standard for analytical testing, method development, and quality control in chemical manufacturing.
