Description

Carbamic Acid, (2,2-Dimercaptoethyl)-, 1,1-Dimethylethyl Ester (9Ci) is a specialized organosulfur compound featuring a carbamate backbone with a dithiol functional group. This unique structure makes it a valuable intermediate for synthesizing complex molecules where the introduction of protected thiol groups is required. It is primarily utilized by research institutions and industrial R&D departments focused on pharmaceuticals, agrochemicals, and advanced material science.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring thiol or disulfide linkages.
• Agrochemical Synthesis: Used in the research and development of novel pesticides and herbicides where the dithiol moiety can act as a metal-chelating or reactive site.
• Peptide Chemistry: Serves as a protected dithiol reagent for the site-specific modification of peptides and proteins.
• Polymer Science: Acts as a monomer or cross-linking agent in the development of specialty polymers with unique redox or adhesive properties.
• Chemical Research: A versatile reagent in organic synthesis for constructing heterocycles or complex molecular architectures.
• Material Science: Investigated for use in creating self-assembled monolayers (SAMs) or surface modifications on metals.
