Description

Bicyclo[3.2.0]Heptan-2-One, 7,7-Difluoro- (9Ci) is a specialized fluorinated bicyclic ketone, a high-value synthetic intermediate prized for its unique structural motif and reactivity. This compound is critical for advanced organic synthesis, particularly in the development of novel pharmaceuticals and agrochemicals where the introduction of fluorine atoms can dramatically alter biological activity and metabolic stability. It is primarily sought after by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials sectors for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of fluorinated active pharmaceutical ingredients (APIs), especially those targeting central nervous system (CNS) disorders and anti-infective agents.
• Agrochemical Research: Used in the development of new-generation herbicides, fungicides, and insecticides, where the difluoro moiety enhances lipophilicity and environmental stability.
• Material Science: Serves as a precursor for specialty polymers and advanced organic electronic materials requiring specific fluorine-containing functional groups.
• Organic Synthesis Reagent: Employed in academic and industrial research for cycloaddition reactions, ring-expansion studies, and as a scaffold for chiral ligand development.
• Flavor & Fragrance Chemistry: Potential intermediate for synthesizing novel musk or amber-type odorants with modified volatility and tenacity.
