Description

Carbamic Acid, (1-Ethenylbutyl)-, 1,1-Dimethylethyl Ester, (R)- (9Ci) is a specialized chiral intermediate of significant importance in advanced organic synthesis. This compound matters for its role as a key building block in the production of enantiomerically pure pharmaceuticals and agrochemicals, where stereochemical control is critical for efficacy and safety. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, biotechnology, and fine chemical industries for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Serves as a crucial chiral synthon in the synthesis of active pharmaceutical ingredients (APIs), particularly for drugs targeting the central nervous system or with specific stereochemical requirements.
• Agrochemical Synthesis: Used in the research and production of enantiomerically pure herbicides, fungicides, and insecticides, where the (R)-configuration can influence biological activity and environmental degradation.
• Asymmetric Catalysis Research: Acts as a substrate or ligand precursor in the development and screening of new asymmetric catalytic reactions in academic and industrial laboratories.
• Fine Chemical Manufacturing: Employed in the multi-step synthesis of complex natural products, flavors, fragrances, and other high-value specialty chemicals requiring precise stereocontrol.
• Process Chemistry & Scale-Up: Provides a defined chiral center for process optimization and kilogram-to-ton scale manufacturing of target molecules in pilot plants and production facilities.
