Product Overview
1-Pentanol, also known as amyl alcohol, is a straight-chain primary alcohol with the molecular formula C5H11OH. This high-purity solvent is characterized by its colorless appearance, mild alcoholic odor, and excellent miscibility with organic solvents while having limited solubility in water. With a boiling point of approximately 138°C and a density of 0.814 g/cm³, it serves as an effective medium for organic synthesis, particularly in esterification and condensation reactions. Its moderate polarity makes it suitable for use in liquid-liquid extraction processes, where it can selectively dissolve non-polar to moderately polar compounds. The analytical grade ensures minimal impurities, with water content typically below 0.1%, making it reliable for sensitive applications like thin-layer chromatography and gas chromatography. The solvent’s low reactivity with most laboratory materials, including glass and stainless steel, enhances its versatility in routine lab procedures. Proper storage in tightly sealed containers away from ignition sources is recommended due to its flammable nature, though its relatively low volatility reduces evaporation losses during extended use.
FAQs
1. What is the typical shelf life of 1-Pentanol when stored properly?
When stored in a cool, dry place in its original tightly sealed container, 1-Pentanol maintains its specified purity for up to 24 months from the date of manufacture. Exposure to air or moisture may gradually reduce its effectiveness.
2. Can this grade of 1-Pentanol be used for spectroscopic analysis?
The analytical grade is suitable for most spectroscopic techniques, though for UV-Vis spectroscopy, additional purification may be required if ultra-low absorbance is critical for your application.
3. What materials should be avoided when handling 1-Pentanol?
Avoid contact with strong oxidizing agents, as violent reactions may occur. It can also degrade certain plastics like polystyrene over prolonged exposure, so glass or HDPE containers are recommended.
4. How does 1-Pentanol compare to other alcohols like ethanol or isopropanol?
1-Pentanol has a higher boiling point and lower volatility than ethanol or isopropanol, making it better suited for applications requiring slower evaporation. Its longer carbon chain also gives it different solubility properties.
5. What’s the recommended disposal method for unused 1-Pentanol?
Small quantities can be evaporated in a fume hood, while larger volumes should be collected as hazardous waste according to local environmental regulations. Never dispose of it in regular waste streams.
