  • Applications

    3-Pyridinemethanol (CAS 100-55-0) is primarily used as a reactive building block in organic synthesis. It serves as an intermediate for the preparation of pyridine-containing pharmaceutical and agrochemical compounds, enabling introduction of a pyridylmethyl moiety. The hydroxyl group allows conversion to esters, ethers, or amines, supporting the synthesis of heterocyclic ligands for catalysis and for functionalized polymers. It also functions as a polyol building block in coatings, adhesives, and specialty polymers via urethane or ester chemistries. Additionally, it may be used as a precursor in dye or pigment chemistry to furnish pyridyl-functionalized derivatives.
