The intricate world of pharmaceutical synthesis relies heavily on specialized chemical compounds that act as crucial intermediates. These molecules are the unsung heroes, providing the structural frameworks and reactive sites necessary to build complex APIs. One such vital compound is 4-Chloro-3-pyridinesulfonamide, identified by its CAS number 33263-43-3. This article explores its multifaceted applications in drug synthesis and the chemical properties that make it an indispensable tool for researchers and manufacturers, brought to you by NINGBO INNO PHARMCHEM CO.,LTD.

At its core, 4-Chloro-3-pyridinesulfonamide is a pyridine derivative characterized by a chlorine atom and a sulfonamide group attached to the pyridine ring. This specific arrangement of functional groups grants it a unique chemical reactivity profile, making it highly valuable in organic synthesis. Typically presented as an off-white to light beige crystalline powder with a purity of 98% or higher, it exhibits a melting point in the range of 150-155°C. These physical and chemical attributes are critical for its use in sensitive synthetic pathways, ensuring consistent and predictable reactions. The molecular formula C5H5ClN2O2S and a molecular weight of approximately 192.62 further define its chemical identity.

One of the most significant applications of 4-Chloro-3-pyridinesulfonamide is in the creation of novel heterocyclic 4-substituted pyridine-3-sulfonamide derivatives. These derivatives are of particular interest in medicinal chemistry due to their potent inhibitory effects on carbonic anhydrase enzymes. Carbonic anhydrases are a family of enzymes involved in various physiological processes, including pH regulation, fluid balance, and CO2 transport. Dysregulation of these enzymes is implicated in several diseases, such as glaucoma, epilepsy, and certain types of cancer. By synthesizing derivatives that selectively inhibit specific carbonic anhydrase isoforms, researchers aim to develop targeted therapies for these conditions. The availability of high-purity 4-Chloro-3-pyridinesulfonamide is thus fundamental for progress in this area of research.

Beyond its role in developing enzyme inhibitors, 4-Chloro-3-pyridinesulfonamide is also a key intermediate in the synthesis of Cefozopran. Cefozopran is a third-generation cephalosporin antibiotic, a class of drugs renowned for their broad-spectrum antibacterial activity and effectiveness against a wide range of pathogens. The chemical backbone provided by 4-Chloro-3-pyridinesulfonamide is integral to the structure of Cefozopran, enabling it to exert its therapeutic effect. The reliable synthesis of such life-saving antibiotics depends on the consistent availability of their constituent intermediates, highlighting the importance of dependable suppliers like NINGBO INNO PHARMCHEM CO.,LTD.
