Description

Benzenesulfonamide, 4-Cyclopropyl- (9Ci) is a specialized aromatic sulfonamide derivative characterized by its unique cyclopropyl substituent. This compound serves as a valuable high-purity chemical intermediate for advanced organic synthesis and pharmaceutical research. It is primarily required by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and material science industries for constructing novel molecular architectures.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of novel active pharmaceutical ingredients (APIs), particularly for candidates targeting central nervous system (CNS) disorders or metabolic diseases.
• Agrochemical Research: Used in the development of new herbicides, fungicides, or plant growth regulators, leveraging the biological activity of the sulfonamide moiety.
• Material Science Precursor: Serves as a monomer or functionalization agent in the production of specialty polymers, resins, or advanced organic frameworks.
• Chemical Biology Probe: Utilized in medicinal chemistry for structure-activity relationship (SAR) studies and as a scaffold for designing enzyme inhibitors.
• Organic Synthesis Reagent: Acts as a versatile intermediate for introducing the sulfonamide functional group into complex molecules via further derivatization.
