Product Overview
Acetic acid (CH₃COOH) is a colorless, pungent-smelling liquid widely used as a key reagent in organic synthesis, biochemical research, and industrial processes. This lab-grade acetic acid features a minimum 99.7% purity, ensuring reliable results in titration, esterification, and protein crystallization experiments. Its hygroscopic nature requires proper storage in tightly sealed containers to prevent moisture absorption. The AR-grade certification guarantees low impurity levels, making it suitable for sensitive applications like chromatography and spectrophotometry. Acetic acid serves as an excellent solvent for polar and non-polar compounds, while its mild acidity (pKa ~4.76) allows controlled pH adjustments in buffer solutions. The product comes in a leak-proof HDPE bottle with child-resistant cap for safe handling. Always use in well-ventilated areas with proper PPE, as concentrated acetic acid can cause severe skin burns and respiratory irritation.
FAQs
1. What is the difference between glacial acetic acid and regular acetic acid?
Glacial acetic acid refers to the pure, water-free form (99.7% concentration) that solidifies at temperatures below 16°C, while regular acetic acid (like vinegar) contains 5-8% acetic acid in water. The glacial form is required for precise laboratory applications where water content would interfere with reactions.
2. Can this acetic acid be used for DNA extraction protocols?
Yes, AR-grade acetic acid is commonly used in DNA extraction for precipitating nucleic acids and adjusting pH during lysis steps, though you may need to dilute it to 3M or 10% solutions depending on your specific protocol requirements.
3. What safety precautions should be taken when handling concentrated acetic acid?
Always wear nitrile gloves, safety goggles, and a lab coat when handling. Work under a fume hood to avoid inhaling vapors. In case of skin contact, immediately rinse with copious amounts of water for at least 15 minutes and seek medical attention for burns.
4. How should I store acetic acid to maintain its purity?
Store in a cool, dry place away from direct sunlight and incompatible substances like oxidizing agents. Keep the bottle tightly sealed to prevent moisture absorption and contamination. The shelf life is typically 2-3 years when stored properly.
5. What are the common impurities found in lower-grade acetic acid?
Lower-grade acetic acid may contain water (most common), formic acid, acetaldehyde, and metal ions like iron or lead. AR-grade acetic acid undergoes rigorous purification to minimize these impurities to ppm levels.
