Product Overview
Isobutyl alcohol AR is a high-purity analytical reagent grade solvent widely used in laboratory settings for its excellent solvency properties and low reactivity. This clear, colorless liquid with a mild characteristic odor is a branched-chain alcohol, offering superior performance in extraction processes, organic synthesis, and chromatographic applications. Its high purity level ensures minimal interference in sensitive analytical procedures, making it a preferred choice for researchers and technicians. The AR grade designation guarantees strict adherence to quality standards, with impurities controlled to trace levels, ensuring reliable and reproducible results in critical applications. Isobutyl alcohol’s moderate evaporation rate and miscibility with many organic solvents make it particularly valuable in sample preparation and purification workflows. The solvent’s stability under normal laboratory conditions contributes to its versatility across various experimental protocols. When stored properly in tightly sealed containers away from ignition sources, this reagent maintains its integrity over extended periods, providing consistent performance throughout its shelf life.
FAQs
1. What is the difference between isobutyl alcohol AR and LR grades?
AR grade isobutyl alcohol meets stricter purity requirements than LR grade, with significantly lower levels of impurities and water content. The analytical reagent grade is specifically manufactured for critical applications where high purity is essential for accurate results, while LR grade is suitable for general laboratory use where extreme purity isn’t required.
2. Can isobutyl alcohol AR be used as a substitute for n-butyl alcohol?
While both are four-carbon alcohols, isobutyl alcohol has a branched structure that gives it different physical properties compared to the straight-chain n-butyl alcohol. The substitution depends on the specific application, as the branched structure can affect solubility, boiling point, and reactivity in certain chemical reactions.
3. What is the typical shelf life of isobutyl alcohol AR when stored properly?
When stored in its original tightly sealed container, away from direct sunlight and moisture, isobutyl alcohol AR typically maintains its specified purity for 2-3 years from the date of manufacture. The actual shelf life may vary depending on storage conditions and frequency of container opening.
4. How should isobutyl alcohol AR be disposed of after use?
Isobutyl alcohol should be disposed of according to local hazardous waste regulations. It should never be poured down drains or mixed with regular waste. Most institutions have specific protocols for solvent disposal, which may involve collection in designated containers for proper treatment or incineration.
5. What safety precautions should be taken when handling isobutyl alcohol AR?
Always use isobutyl alcohol in a well-ventilated area or under a fume hood, as it can release harmful vapors. Wear appropriate personal protective equipment including safety goggles, gloves, and lab coat. Avoid all sources of ignition, as the solvent is highly flammable. In case of skin contact, wash immediately with plenty of water.
