Description

Cyclopentanecarbonyl Chloride, 3-Chloro-1,3-Dimethyl-2-Oxo-, trans- (9Ci) is a high-purity, specialized organic intermediate of significant importance in advanced synthetic chemistry. Its core value lies in its reactive acid chloride functionality and chiral, substituted cyclopentane ring, making it a critical building block for constructing complex molecular architectures. This compound is primarily needed by research and development teams in the pharmaceutical and agrochemical industries for the synthesis of novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of complex drug candidates, particularly those targeting central nervous system (CNS) disorders, metabolic diseases, and anti-inflammatory agents.
• Agrochemical Synthesis: Used in the research and development of novel pesticides, herbicides, and fungicides, leveraging its structural complexity for enhanced biological activity.
• Advanced Material Precursor: Serves as a monomer or cross-linking agent in the development of specialty polymers and liquid crystals with specific optical or mechanical properties.
• Chiral Synthesis: The trans- configuration provides a defined stereocenter, making it valuable for asymmetric synthesis and the production of enantiomerically pure compounds.
• Chemical Research & Development: Employed in academic and industrial R&D labs for methodological studies, library synthesis, and exploring new reaction pathways in organic chemistry.
• Fine Chemical Production: Integral to the multi-step synthesis of high-value, low-volume specialty chemicals used in electronics, catalysis, and fragrance industries.
