Description

Carbamic Acid, [2-(2-Oxoethoxy)Ethyl]-, 1,1-Dimethylethyl Ester (9Ci) is a specialized carbamate derivative, also known as a tert-butyl-protected amino alcohol ester. This compound serves as a critical building block and protecting group reagent in advanced organic synthesis, offering controlled reactivity for the development of complex molecules. It is primarily required by pharmaceutical R&D laboratories and fine chemical manufacturers engaged in the synthesis of active pharmaceutical ingredients (APIs), agrochemicals, and other high-value specialty chemicals.

Application

• Pharmaceutical Intermediate: A key synthon in the multi-step synthesis of novel drug candidates and active pharmaceutical ingredients (APIs).
• Amino Group Protection: Utilized as a tert-butyloxycarbonyl (Boc)-type protecting group for amines in complex organic synthesis, preventing unwanted side reactions.
• Peptide Chemistry: Employed in the synthesis of peptide analogs and modified amino acids where selective protection is required.
• Agrochemical Synthesis: Serves as a precursor or intermediate in the manufacture of advanced herbicides, fungicides, and plant growth regulators.
• Material Science Research: Used in the development of functional polymers, dendrimers, and other specialty materials requiring specific amine functionalities.
• Cross-Coupling Reactions: Acts as a substrate or reagent in palladium-catalyzed and other metal-mediated coupling reactions to form carbon-heteroatom bonds.
