Description

4-Mercaptopyridine is a versatile heterocyclic building block featuring both a pyridine ring and a reactive thiol group. This bifunctional structure makes it a critical intermediate for synthesizing complex molecules in pharmaceutical and agrochemical research. It is particularly valuable for researchers and manufacturers developing active pharmaceutical ingredients (APIs), ligands for catalysis, and functional materials. The compound is supplied as a high-purity solid to ensure reliable performance in sensitive synthetic applications.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly in kinase inhibitor and antiviral research.
• Ligand Synthesis: Used to prepare thiol-containing ligands for metal complexes in homogeneous catalysis and material science.
• Agrochemical Development: Serves as a precursor in the creation of new pesticides and herbicides.
• Chemical Research: Employed in organic synthesis to introduce the pyridylthiol moiety into more complex molecular architectures.
• Material Science: Can be used to modify surfaces or create functional polymers due to its reactive thiol group.

Quality Control

Our 4-Mercaptopyridine is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and spectroscopic identification (IR, NMR), to ensure it meets the high standards required for research and development. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay and impurity profiles.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers.
