Description

2-Thiophenesulfonamide,4-Amino-(8Ci,9Ci) is a specialized heterocyclic sulfonamide derivative that serves as a critical building block in advanced chemical synthesis. Its unique molecular structure, featuring both an amino group and a sulfonamide moiety on a thiophene ring, makes it a valuable intermediate for creating compounds with targeted biological and material properties. This high-purity intermediate is essential for research and development in the pharmaceutical and agrochemical industries, where it is used to develop new active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel drug candidates, particularly those targeting specific enzymes or receptors where the thiophene-sulfonamide scaffold is pharmacologically active.
• Agrochemical Research: Used in developing new generations of herbicides, fungicides, and insecticides, leveraging its heterocyclic structure for enhanced bioactivity and selectivity.
• Material Science: Serves as a monomer or functionalizing agent in the production of specialty polymers, dyes, and organic electronic materials due to its electron-rich thiophene core.
• Chemical Synthesis: Acts as a versatile building block for further functionalization, enabling the creation of complex sulfonamide libraries for high-throughput screening and discovery chemistry.
• Bioconjugation & Probe Development: The reactive amino group allows for coupling to biomolecules or fluorescent tags, making it useful in diagnostic probe and bioconjugate synthesis.

Quality Control

Our 2-Thiophenesulfonamide,4-Amino-(8Ci,9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous 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. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled 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.
