3-methoxybutanol

3-Methoxybutanol (CAS 2517-43-3) is a glycol ether-type solvent.

Where is 3-methoxybutanol used?

• Metalworking and industrial cleaning: co-solvent in degreasing compounds and aqueous cleaning concentrates where controlled evaporation is required
• Printing and packaging: incorporated into ink systems to improve flow, open time, and adhesion on difficult substrates
• Coatings: optimizes viscosity and film formation in waterborne and solvent-borne systems
• Personal care: carrier solvent in hair care products and skin cleansers
• Formulators use it for managing solvent balance and substrate compatibility.

Good to know: Slow evaporation and miscibility with water and organic solvents; often preferred over more aggressive alternatives when a mild, slow-evaporating solvent is necessary.

Commercial specifications

• Purity specifications generally range from 98% upward
• Clear liquid, typically in drum and IBC quantities
• COA and SDS available for regulatory and QA review
