Product Overview
tert-Butyl alcohol AR (2-Methyl-2-propanol) is a high-purity, colorless liquid with a camphor-like odor, widely used as a solvent and intermediate in organic synthesis. With a purity of 99.5%, this AR-grade reagent ensures minimal impurities, making it suitable for sensitive laboratory applications. Its low toxicity and non-corrosive nature enhance safety during handling, while its miscibility with water and organic solvents broadens its utility in extractions and purification processes. The compound’s high boiling point (82.4°C) and low freezing point (25.5°C) provide stability across varied experimental conditions. As a tertiary alcohol, it resists oxidation, ensuring consistent performance in reactions. The 500 ml pack size offers convenience for frequent lab use without excessive storage concerns. Compatible with most glassware and standard lab equipment, tert-Butyl alcohol AR maintains integrity in both acidic and basic environments, though it should be stored in tightly sealed containers to prevent moisture absorption. Its versatility extends to use as a denaturing agent and in the preparation of tert-butyl esters, further solidifying its role as an essential lab reagent.
FAQs
1. What is the shelf life of tert-Butyl alcohol AR when stored properly?
When stored in a cool, dry place in its original tightly sealed container, tert-Butyl alcohol AR retains its stability for up to 24 months from the date of manufacture. Avoid exposure to direct sunlight or heat sources to prevent degradation.
2. Can tert-Butyl alcohol AR be used as a substitute for isopropyl alcohol in cleaning applications?
While both are alcohols, tert-Butyl alcohol AR is not typically recommended for general cleaning due to its higher cost and specialized lab-grade purity. It lacks the broad-spectrum disinfectant properties of isopropyl alcohol and is better suited for chemical synthesis.
3. Is this product compatible with plastic containers for long-term storage?
tert-Butyl alcohol AR is best stored in glass containers, as prolonged contact with certain plastics (e.g., polyethylene or polypropylene) may lead to leaching or container degradation. Use HDPE or PTFE-lined containers if plastic is unavoidable.
4. What precautions should be taken when handling tert-Butyl alcohol AR in a fume hood?
Always wear nitrile gloves, safety goggles, and a lab coat to avoid skin or eye contact. Ensure adequate ventilation, as vapors can cause dizziness or irritation. Avoid open flames, as the alcohol is flammable with a flash point of 11°C.
5. How does tert-Butyl alcohol AR differ from reagent-grade tert-Butyl alcohol?
AR (Analytical Reagent) grade tert-Butyl alcohol undergoes stricter purification processes to meet higher purity standards (typically ≥99.5%) compared to general reagent-grade variants. This reduces interference in analytical techniques like chromatography or spectroscopy.
