Description

3-Aminopropanol CAS NO 156-87-6 is a versatile amino alcohol, also known as 3-amino-1-propanol, featuring both a primary amino group and a primary hydroxyl group on a three-carbon chain. This bifunctional structure makes it a valuable intermediate and building block for the synthesis of a wide range of specialty chemicals. It is primarily sought by industries involved in pharmaceuticals, agrochemicals, and polymer production for its reactivity and ability to introduce both amine and alcohol functionalities into target molecules.

Application

• Pharmaceutical Intermediates: Key building block for synthesizing active pharmaceutical ingredients (APIs), including antimalarial drugs, local anesthetics, and β-blockers.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators.
• Polymer & Resin Modifier: Serves as a monomer or chain extender in polyurethane and epoxy resin systems, imparting flexibility and adhesion properties.
• Corrosion Inhibitors: An essential component in formulations for metalworking fluids and cooling water treatments.
• Surfactants & Detergents: Used to produce amphoteric and cationic surfactants for personal care and industrial cleaning products.
• Gas Treating Agent: Employed in formulations for acid gas (CO₂, H₂S) scrubbing in natural gas processing and refining.
• Bioconjugation & Linker Chemistry: Utilized in biochemical research and diagnostics for coupling biomolecules.
