Product Description
1-Propanol (n-Propanol) is a colorless, flammable liquid with an alcohol-like odor. It is a primary alcohol with good solvent properties and is used in chemical manufacturing, industrial cleaning, coatings, inks, and other formulation applications.
Due to its solvent performance and volatility, 1-propanol can be used in selected industrial processes where compatibility, evaporation characteristics, and product purity are important. Available grades may vary according to purity and intended application.
Safety and Storage
1-Propanol is flammable. Keep it away from heat, sparks, open flames, and other ignition sources. Use it in a well-ventilated area and wear suitable personal protective equipment. Avoid inhalation of vapors and contact with eyes and skin.
Store in a tightly closed, compatible container in a cool, well-ventilated area. Follow applicable regulations and consult the product-specific Safety Data Sheet (SDS) before handling.
