Description

Carbamic Acid, [1-(Mercaptomethyl)-2-Propenyl]-, Ethyl Ester (9Ci) is a specialized organosulfur compound featuring a unique mercaptomethyl-propenyl functional group. This molecular structure makes it a valuable intermediate for synthesizing complex molecules, particularly in pharmaceutical and agrochemical research. It is sought after by R&D chemists and process development scientists working on novel active ingredients, polymer modifiers, and advanced material precursors.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly those targeting cysteine proteases or requiring thiol-reactive moieties.
• Agrochemical Research: Used in developing new pesticides and herbicides where the thiol and ester groups can be leveraged for bioactivity or as a synthetic handle.
• Polymer Chemistry: Acts as a functional monomer or cross-linking agent for creating specialty polymers with tailored properties like adhesion or reactivity.
• Chemical Synthesis: Serves as a versatile intermediate in organic synthesis for introducing protected thiol and carbamate functionalities into target molecules.
• Material Science: Potential use in surface modification and the creation of self-assembled monolayers (SAMs) on metal surfaces.
• Bioconjugation: Useful in developing linkers for antibody-drug conjugates (ADCs) or protein labeling due to its reactive thiol group.
