Isobutyl Alcohol 99% ACS Grade

Product Overview

Isobutyl Alcohol 99% ACS Grade, also known as 2-Methyl-1-propanol, is a high-purity branched-chain aliphatic alcohol designed for analytical and industrial applications. With a molecular formula of C₄H₁₀O and a molecular weight of 74.12 g/mol, this solvent offers low volatility and strong solvency across a wide range of organic substrates. The ACS Reagent Grade specification ensures batch-to-batch consistency and a clean spectral profile, making it suitable for chromatographic applications, coatings formulation, and chemical synthesis. The product exhibits a clear, colorless appearance with a characteristic alcohol odor, and is prepared to minimize impurities such as aldehydes and halides to support sensitive analytical methods and high-purity requirements.

The solvent is optimized for use in environments requiring precise quality control: the 20°C specific gravity is around 0.786 g/mL, the refractive index at 20°C is 1.396, and the flash point is 11°C, indicating a controlled handling profile for storage and transport. Its limited acidity (meq/g) and low impurity levels—verified via rigorous testing (e.g., ICP-OES for trace metals, ion chromatography for anions)—help maintain baseline stability in HPLC, UV-Vis, and other analytical workflows. ACS and USP-NF monograph compliance further reinforce its suitability for laboratory and manufacturing applications that demand reliability and regulatory alignment.

Safety Precautions

Store in a cool, dry place away from heat sources and open flames. Use compatible containers (HDPE or glass) and ensure proper ventilation during handling to minimize inhalation exposure; wear PPE including gloves and safety goggles. The product is flammable and should be kept away from ignition sources and incompatible materials to prevent accidents.

In case of exposure, follow standard emergency procedures: for eyes, rinse cautiously with water for several minutes; for skin, wash with soap and water and seek medical advice if irritation occurs; for inhalation, move to fresh air and monitor for dizziness or drowsiness; for ingestion, rinse mouth and do not induce vomiting unless advised by a poison control center. Refer to the SDS for complete instructions and first-aid measures.
