Description

Cyclopropanecarbonitrile is a versatile and high-value organic nitrile building block characterized by its strained three-membered cyclopropane ring. This unique structure makes it a critical intermediate in the synthesis of complex molecules, particularly in the pharmaceutical and agrochemical sectors. It is primarily sought after by R&D chemists and process development scientists for constructing novel active ingredients and advanced materials. Our supply of Cyclopropanecarbonitrile CAS NO 5500-21-0 ensures high purity and batch-to-batch consistency for demanding synthetic applications.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), especially those containing cyclopropane motifs for enhanced metabolic stability and bioavailability.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides where the cyclopropane ring contributes to biological activity.
• Organic Synthesis Building Block: Employed in ring-opening reactions, [2+1] cycloadditions, and as a starting material for cyclopropane-containing carboxylic acids, esters, and amines.
• Material Science Research: Serves as a monomer or cross-linking agent in the development of specialty polymers and advanced functional materials.
• Chemical Biology Probes: Utilized in medicinal chemistry for creating molecular probes and labeled compounds due to its reactive nitrile group.
