Wear appropriate personal protective equipment to avoid direct contact with skin and eyes. During the operation, care should be taken to avoid inhaling dust and avoiding contact with the skin. If inhaled or ingested by mistake, seek medical attention immediately. Specific safety practice guidelines can be referenced from the safety data sheets provided by the supplier of the chemical used.
Application
4-Aminopyridine-2-carboxylic acid (CAS 100047-36-7) is a versatile heterocyclic building block widely used in medicinal chemistry and drug discovery. The presence of both an amino group at the 4-position and a carboxylic acid at the 2-position enables diverse functionalization, including amide bond formation, heterocycle annulation, and cross-coupling reactions. This scaffold is a key intermediate for the synthesis of potent kinase inhibitors targeting cancer, inflammation, and autoimmune diseases (e.g., JAK, BTK, CDK inhibitors). It also serves as a precursor for antiviral, antibacterial, and antifungal agents. Its rigid, hydrogen-bond-capable pyridine core enhances target binding affinity and metabolic stability. High purity ensures reproducible results in high-throughput screening, SAR studies, and scalable GMP manufacturing. Xinchem offers custom synthesis, custom chemical synthesis, and contract manufacturing of this essential intermediate with flexible scaling from R&D to commercial tons.
