Product Overview
n-Butanol, also known as 1-butanol or butyl alcohol, is a four-carbon straight-chain alcohol widely used as a laboratory solvent due to its balanced polarity and low volatility. This high-purity (99.5% minimum) analytical-grade reagent is manufactured under strict quality controls to ensure minimal impurities, making it suitable for precise applications where consistency is critical. Its moderate boiling point (117-118°C) allows for controlled evaporation, while the low water solubility (7.7 g/100 mL at 20°C) enables selective extraction processes. The solvent exhibits excellent miscibility with most organic compounds, including ethers, ketones, and hydrocarbons, while remaining stable under standard lab conditions. Its mild odor and non-corrosive nature simplify handling, though standard PPE is recommended. The product is packaged in HDPE bottles with tamper-evident seals to prevent contamination during storage or transport. Each batch undergoes rigorous GC-MS testing to verify purity, with certificates of analysis available upon request. The 100 ml pack size offers convenience for small-scale experiments while maintaining cost efficiency for frequent users.
FAQs
1. What is the shelf life of n-Butanol when stored properly?
When stored in tightly sealed original containers at room temperature away from direct sunlight and moisture, n-Butanol maintains its specified purity for 24 months from the date of manufacture. Always check the expiration date on the label before use.
2. Can this n-Butanol be used as a substitute for ethanol in DNA precipitation?
While n-Butanol can be used in some precipitation protocols, it behaves differently from ethanol due to its lower polarity and higher molecular weight. Protocol adjustments including concentration ratios and incubation times would be necessary for equivalent results.
3. What safety precautions should be taken when handling this solvent?
Always use n-Butanol in a well-ventilated area or under a fume hood, as prolonged inhalation of vapors may cause dizziness. Wear nitrile gloves, safety goggles, and a lab coat to prevent skin and eye contact. Avoid open flames as the solvent is flammable.
4. How does the purity of this n-Butanol compare to reagent-grade alternatives?
This laboratory-grade n-Butanol meets 99.5% minimum purity specifications, making it comparable to most reagent-grade products available in the market. The primary difference lies in the certification documentation, with reagent grade typically including more comprehensive impurity profiling.
5. What type of container is recommended for long-term storage of opened bottles?
For opened bottles requiring long-term storage, transfer the solvent to amber glass bottles with PTFE-lined caps to minimize light exposure and prevent potential leaching from plastic containers. Ensure the container is completely dry before transfer to avoid moisture contamination.
