Description

Carbamic Acid, (2-Mercapto-2-Methylpropyl)-, 1,1-Dimethylethyl Ester (9Ci) is a specialized organosulfur compound featuring a protected mercaptan (thiol) group, making it a valuable intermediate in advanced organic synthesis. Its core value proposition lies in its ability to act as a versatile building block for introducing thiol functionalities under controlled conditions, which is critical for developing pharmaceuticals, agrochemicals, and functional materials. This product is essential for R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries who require high-purity, reliable intermediates for complex molecule construction.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly those containing thioether or disulfide linkages.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and insecticides where the thiol group is incorporated for biological activity.
• Polymer Modification: Serves as a chain transfer agent or functional monomer in the synthesis of specialty polymers with tailored properties.
• Peptide Chemistry: Employed for the introduction of protected cysteine analogs or for creating disulfide bridges in peptide synthesis.
• Ligand and Catalyst Development: Useful precursor for synthesizing sulfur-containing ligands used in metal catalysis and coordination chemistry.
• Material Science Research: Intermediate in creating self-assembled monolayers (SAMs) or surface-modifying agents on gold and other metals.
