Description

Carbamic Acid, [(1S)-1-Ethyl-2-Propenyl]-, 1,1-Dimethylethyl Ester (9Ci) is a specialized chiral intermediate of significant interest in advanced organic synthesis. This compound matters for its role as a key building block in the development of enantiomerically pure pharmaceuticals and agrochemicals, where stereochemical control is critical. It is primarily needed by research institutions and industrial R&D departments focused on creating novel active ingredients, particularly in the fields of medicinal chemistry and crop protection.

Application

• Pharmaceutical Intermediate: Serves as a crucial chiral synthon in the multi-step synthesis of potential drug candidates, especially those targeting central nervous system (CNS) disorders or infectious diseases.
• Agrochemical Research: Used in the development of new, stereoselective pesticides and herbicides, where the specific spatial orientation of the molecule can influence biological activity and environmental degradation.
• Asymmetric Synthesis: Employed in catalytic and stoichiometric asymmetric reactions to construct complex molecular architectures with high enantiomeric excess.
• Process Chemistry Development: Utilized for scaling up synthetic routes from laboratory to pilot plant scale, optimizing yield and purity for cost-effective production.
• Academic & Contract Research: A valuable reagent for universities and CROs (Contract Research Organizations) investigating new synthetic methodologies or structure-activity relationships (SAR).
