Description

Carbamic Acid, (Isocyanatomethyl)-, 1,1-Dimethylethyl Ester (9Ci) is a specialized organic compound belonging to the class of protected isocyanate derivatives. This chemical serves as a crucial building block in advanced organic synthesis, offering a reactive isocyanate group masked with a tert-butyl ester for controlled reactivity and enhanced stability. It is primarily sought after by research and development chemists in the pharmaceutical and agrochemical industries for constructing complex molecular architectures, such as ureas and carbamates, which are key motifs in active ingredient development.

Application

• Pharmaceutical Intermediate: A key synthon for the synthesis of urea-based active pharmaceutical ingredients (APIs) and prodrugs.
• Agrochemical Synthesis: Used in the research and production of novel herbicides, fungicides, and insecticides requiring carbamate or urea linkages.
• Polymer Chemistry: Serves as a monomer or cross-linking agent in the development of specialty polyurethanes and other functional polymers.
• Peptide Modification: Employed in bioconjugation and peptide chemistry to introduce isocyanate functionality under mild conditions.
• Chemical Research: A valuable reagent in academic and industrial R&D for exploring new organic reactions and material science applications.
• Custom Synthesis: Used by contract research and manufacturing organizations (CROs/CMOs) for client-specific molecule construction.

Quality Control

Our Carbamic Acid, (Isocyanatomethyl)-, 1,1-Dimethylethyl Ester (9Ci) is produced under strict quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) documenting batch-specific results are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
