Isobutyl Alcohol 99%

Product Overview

Isobutyl Alcohol 99% (also known as Isobutanol or 2-Methyl-1-propanol) is a colorless, flammable liquid solvent characterized by a distinct alcohol odor. This high-purity C₄H₁₀O solvent meets ACS Reagent Grade standards, ensuring specific gravity and refractive index stability for demanding industrial applications. It serves as a critical intermediate in the production of esters and plasticizers and is widely utilized as a solvent in coatings and lacquers.

Our Isobutyl Alcohol offers robust miscibility with organic solvents and water, making it an effective component in HPLC mobile phases and extraction processes. Stringent manufacturing controls maintain low aldehyde and chloride levels, ensuring consistent performance across batches. Alliance Chemical supplies this material in a wide range of pack sizes, from lab-scale quantities to bulk 330-gallon totes, to support diverse manufacturing and research requirements.
