Description

Cyclopropanecarboxaldehyde, 2-Butyl-2-Ethynyl- (9Ci) is a specialized organic building block featuring a cyclopropane ring, a butyl chain, and an ethynyl (acetylene) group attached to an aldehyde functionality. This unique molecular architecture makes it a valuable intermediate for synthesizing complex molecules in advanced research and development. It is primarily sought after by pharmaceutical and agrochemical R&D teams for constructing novel active ingredients and by academic researchers exploring new chemical spaces in medicinal chemistry and materials science.

Application

• Pharmaceutical Intermediate: Key synthon for the development of novel drug candidates, particularly in areas requiring constrained, three-dimensional structures.
• Agrochemical Research: Used in the synthesis of new-generation pesticides and herbicides, leveraging its reactive aldehyde and alkyne groups.
• Organic Synthesis Building Block: Serves as a versatile precursor for cyclopropane-containing compounds, heterocycles, and complex natural product analogs.
• Material Science Research: Potential monomer or cross-linking agent in the development of specialty polymers with unique thermal or mechanical properties.
• Chemical Biology Probes: Useful for creating labeled compounds or probes due to the reactive ethynyl group, which can participate in click chemistry reactions.
