Why Isobutyl Alcohol 99% ACS Grade

Isobutyl Alcohol 99% ACS Grade delivers the rigorous purity and exact evaporation profile required for precise analytical testing and advanced industrial manufacturing. By meeting strict American Chemical Society standards, this clear, colorless C4H10O liquid guarantees extremely low non-volatile matter and trace impurities, preventing unwanted residue in sensitive operations. With a flash point of 28, it provides a stable, medium-boiling aliphatic alcohol option that is highly soluble in water, ether, and other organic solvents. Buyers select this specific grade when they need reliable solvency power in petroleum processing, wastewater extraction protocols, and specialized analytical applications where batch-to-batch chemical consistency is critical for preventing process contamination.

Best Applications for This Grade

  • Commonly applied in specialized wastewater treatment protocols as a highly soluble extraction agent to separate complex organic compounds from aqueous effluent layers before final discharge.
  • Functions as a precise solvent and flow promoter commonly applied in industrial surface coatings, where its slow evaporation rate helps control the drying process, leveling the finish and preventing moisture blushing under high humidity.
  • Acts as a highly pure chemical intermediate commonly applied in petroleum extraction, refining, and additive manufacturing environments where exact ACS specifications prevent unwanted trace metal contamination from degrading downstream catalysts.
  • Serves as a reliable solvent matrix commonly applied in analytical laboratories and testing facilities for liquid chromatography, relying on its guaranteed 99% concentration and extremely low non-volatile residue to ensure baseline stability.

When to Choose a Different Grade

  • If your industrial manufacturing process or wastewater extraction protocol demands a standard 99% concentration but does not require the strict analytical certification, trace metal limits, and low-residue guarantees of the ACS specification, select Isobutyl Alcohol 99% to optimize operational costs.
  • If you require a ketone-based solvent rather than an alcohol, specifically one offering a faster evaporation profile and stronger solvency power for dissolving complex vinyl or acrylic resins while still maintaining analytical testing purity, choose Methyl Isobutyl Ketone (MIBK) ACS Grade.
  • If your facility needs a medium-boiling ketone solvent commonly applied in heavy-duty industrial degreasing, machinery maintenance, or bulk chemical extraction where certified analytical purity and zero-residue finishes are unnecessary, opt for Methyl Isobutyl Ketone (MIBK) Technical Grade.
