Description

5-Chloro-3-Methylbenzo[B]Thiophene-2-Sulfonamide is a high-purity, specialized organic intermediate of significant importance in advanced chemical synthesis. Its core value lies in its functionalized benzothiophene scaffold, which serves as a critical building block for the development of novel active pharmaceutical ingredients (APIs) and agrochemicals. This compound is primarily needed by research institutions and manufacturers in the pharmaceutical, agrochemical, and material science industries for creating new molecules with targeted properties.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel drug candidates, particularly those targeting enzyme inhibition or receptor modulation.
• Agrochemical Research: Used in the development of new herbicides, fungicides, and insecticides, leveraging its heterocyclic structure for biological activity.
• Material Science: Serves as a building block for organic electronic materials, such as semiconductors or charge-transport materials, due to the electron-rich thiophene core.
• Chemical Synthesis: Employed in organic chemistry research for constructing complex polycyclic structures via cross-coupling and cyclization reactions.
• Dye & Pigment Intermediate: Potential use in the synthesis of specialized dyes and pigments where the sulfonamide and chloro groups offer sites for further functionalization.

Quality Control

Our 5-Chloro-3-Methylbenzo[B]Thiophene-2-Sulfonamide is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the high standards required for research and commercial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment and is available upon request.

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 after opening to prevent degradation from atmospheric moisture.
