Description

Carbamic Acid, [2-(Methoxymethoxy)Ethyl]-, 1,1-Dimethylethyl Ester (9Ci) is a specialized carbamate derivative featuring a tert-butyl ester group and a methoxymethoxyethyl side chain, serving as a versatile and protected synthetic intermediate. Its primary value lies in providing a reactive handle for the controlled introduction of amine functionalities in complex organic synthesis, particularly in the development of active pharmaceutical ingredients (APIs). This compound is essential for research chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials sectors who require high-purity, structurally defined building blocks.

Application

• Pharmaceutical Intermediate: Key building block in the multi-step synthesis of novel drug candidates, especially those requiring protected amine or carbamate linkages.
• Agrochemical Synthesis: Used in the research and development of new pesticides, herbicides, and fungicides where its specific carbamate structure is incorporated into the active molecule.
• Peptide Mimetics & PROTACs: Serves as a precursor for constructing peptide-like chains or linkers in complex molecules like proteolysis-targeting chimeras (PROTACs).
• Polymer Chemistry: Acts as a monomer or functionalization agent for creating specialty polymers with tailored properties, such as polyurethanes or polycarbonates.
• Chemical Biology Probes: Utilized in the synthesis of labeled compounds or probes for studying biological mechanisms and enzyme interactions.
• Custom Synthesis & Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for custom synthesis projects requiring this specific molecular scaffold.
