Isobutyl Alcohol 99% ACS Grade

Product Overview

Isobutyl Alcohol 99% ACS Grade (CAS 78-83-1), also known as 2-Methyl-1-propanol or Isobutanol, is a high-purity branched-chain aliphatic alcohol. Engineered for analytical and industrial applications, this solvent offers low volatility and strong solvency across a wide range of organic substrates. As an ACS Reagent Grade chemical, it meets strict specifications for purity, ensuring batch-to-batch consistency essential for chromatographic applications (HPLC), coatings formulation, and chemical synthesis.

The product appears as a clear, colorless liquid with a characteristic alcohol odor. It is meticulously processed to minimize impurities such as aldehydes, halides, and water, supporting sensitive analytical methods. With a specific gravity of approximately 0.786 and a refractive index of 1.396, it provides a stable baseline for UV-Vis and other detection workflows.

Safety Precautions

Isobutyl Alcohol is flammable and must be handled with care. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flames. Keep containers tightly closed when not in use. Use appropriate personal protective equipment (PPE), including solvent-resistant gloves and safety goggles, to prevent skin and eye contact.

In the event of exposure, rinse eyes with water for several minutes and wash skin thoroughly with soap and water. If inhaled, move to fresh air immediately. Refer to the Safety Data Sheet (SDS) for detailed handling and emergency response procedures.
