Description

2-Pyridinesulfonamide,4-Amino-(9Ci) is a specialized heterocyclic sulfonamide derivative, serving as a critical building block in advanced organic synthesis. Its value lies in its bifunctional structure, combining an amino group and a sulfonamide moiety on a pyridine scaffold, which enables its use in constructing complex pharmacologically active molecules. This high-purity intermediate is primarily needed by research institutions and pharmaceutical companies engaged in the development of new active pharmaceutical ingredients (APIs) and agrochemicals.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, particularly those targeting enzymes where sulfonamide groups act as bioisosteres.
• Agrochemical Research: Used in developing new generations of herbicides and fungicides, leveraging its heterocyclic structure for biological activity.
• Ligand Synthesis: Serves as a starting material for creating complex chelating ligands in coordination chemistry and catalysis.
• Material Science: Potential monomer or additive in the synthesis of specialty polymers with specific electronic or binding properties.
• Chemical Biology: Employed in the design and synthesis of molecular probes and enzyme inhibitors for biochemical research.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
