Butanol Extra Pure
Original price was: $ 35.00.$ 34.76Current price is: $ 34.76.
Butanol Extra Pure is a high-purity aliphatic alcohol commonly used in laboratory environments as a solvent, reagent, and intermediate in organic synthesis. Its moderate polarity and ability to dissolve a wide range of compounds make it ideal for use in extractions, chromatography, and spectrophotometric analysis. It also serves as a starting material for producing esters, plasticizers, and pharmaceuticals. The 99.4% purity ensures minimal water and impurity content, providing reliable consistency in sensitive procedures. With a relatively low evaporation rate and good miscibility with many organic solvents, it is suitable for both preparative and analytical applications. Proper storage in a cool, ventilated area in tightly sealed containers is essential to preserve its quality and reduce volatility.
