Description

Carbamic Acid, (2-Chloro-2-Methyl-3-Butynyl)-, Methyl Ester (9Ci) CAS NO 91434-62-7 is a specialized organic building block featuring a unique combination of a carbamate ester group and a reactive chloroalkyne moiety. This molecular architecture makes it a valuable intermediate for the synthesis of complex molecules, particularly in advanced pharmaceutical and agrochemical research. It is primarily sought after by R&D chemists and process development scientists working on novel active ingredients, where its functional groups enable strategic bond formation and structural diversification.

Application

• Pharmaceutical Intermediate: Key synthon for constructing nitrogen-containing heterocycles and complex pharmacophores in drug discovery programs.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides, leveraging its reactive alkyne and chloro groups.
• Chemical Biology Probe Development: Serves as a precursor for click chemistry reagents and activity-based probes due to the terminal alkyne functionality.
• Material Science Research: Potential monomer or cross-linking agent for creating polymers with specific functional properties.
• Custom Synthesis & Contract Manufacturing: A critical starting material for custom synthesis houses producing high-value, low-volume specialty chemicals for clients.
