3-Amino-1-butanol丨CAS 2867-59-6

3-Amino-1-butanol (CAS 2867-59-6) is a versatile organic intermediate widely used in pharmaceutical, polymer, and chemical synthesis. In pharmaceuticals, it serves as a building block for the synthesis of β-blockers, antiviral agents, and other bioactive molecules, providing both an amino and a hydroxyl functionality for further derivatization. It is also used in the production of specialty chemicals such as surfactants, corrosion inhibitors, and chelating agents. In polymer chemistry, 3-amino-1-butanol is utilized as a monomer or chain extender for polyurethanes, polyesters, and other specialty polymers, enhancing flexibility, adhesion, and chemical resistance. Its bifunctional structure makes it a valuable reagent for multistep synthetic pathways, enabling selective modification and incorporation into complex molecular frameworks.

The benefits of 3-amino-1-butanol arise from its dual functional groups, chemical stability, and solubility in both aqueous and organic solvents. The primary amino group allows for efficient acylation, alkylation, or condensation reactions, while the hydroxyl group provides additional reactive handles for etherification, esterification, or polymer formation. Its relatively low toxicity, ease of handling, and compatibility with common reagents make it practical for laboratory and industrial use. Moreover, its bifunctionality enables streamlined synthesis of multifunctional molecules, improving reaction efficiency and reducing the number of synthetic steps required. These properties make it particularly useful in designing pharmaceuticals, specialty chemicals, and functional polymers.
