Product Name – n-BUTANOL 99% AR Quantity/Pack Size – 500 ml, 1 L Form – Liquid Grade – AR (Analytical Reagent) Application – Solvent, extraction, synthesis
Product Overview
n-BUTANOL 99% AR is a high-purity primary alcohol solvent designed for laboratory applications requiring moderate polarity and a high boiling point. This analytical reagent-grade butanol undergoes rigorous purification to remove water, aldehydes, and other impurities, ensuring consistent performance in liquid-liquid extractions, chromatographic separations, and organic synthesis. Its balanced hydrophilic-lipophilic properties make it an excellent choice for fractionating complex mixtures, while its high boiling point (117.7°C) enables selective extractions without excessive evaporation. Unlike technical-grade butanol, this product is free from denaturants, making it suitable for sensitive analytical techniques like GC and HPLC. The solvent’s miscibility with water and organic solvents enhances its versatility in reaction media and sample preparation. Packaged in airtight containers, it maintains purity during storage, minimizing moisture absorption. Whether used for isolating natural products, as a mobile phase modifier in chromatography, or for synthesizing esters and plastics, this n-butanol delivers precision and reliability for advanced laboratory applications.
FAQs
1. Can n-butanol be used for DNA precipitation?
It is less common than ethanol or isopropanol but can be used in specific protocols for large DNA fragments.
2. How does n-butanol compare to tert-butanol?
n-Butanol is less soluble in water and has a higher boiling point, affecting its use in extractions.
3. Is this butanol suitable for HPLC?
Yes, but it may require filtration to remove particulates before use as a mobile phase.
4. Can n-butanol replace ethanol in extractions?
In some cases, but its lower polarity may reduce extraction efficiency for polar compounds.
5. How should n-butanol be stored?
Store in a cool, dry place in tightly sealed containers to prevent moisture absorption.
