Product Overview

ACETONITRILE 99.5% AR is a high-purity, ultra-low-water solvent designed for critical laboratory applications where consistency and minimal impurities are essential. This analytical reagent (AR) grade acetonitrile undergoes rigorous purification to ensure ≤0.03% water content, making it ideal for high-performance liquid chromatography (HPLC), UV/Vis spectroscopy, and organic synthesis. Its low UV absorbance and high polarity enhance separation efficiency and detection sensitivity in chromatographic techniques. The solvent’s stability under varying temperatures and resistance to oxidation ensure reliable performance in long-duration experiments. Packaged in amber glass bottles to prevent photodegradation, this acetonitrile maintains its integrity during storage and transport. Its compatibility with a wide range of organic and inorganic compounds further expands its utility in extraction, recrystallization, and reaction media. Whether used as a mobile phase in HPLC or a solvent for sample dissolution, this AR-grade acetonitrile delivers reproducible results with minimal baseline noise, reducing the need for frequent column cleaning or recalibration.

FAQs

1. What is the water content in ACETONITRILE 99.5% AR?

The water content is ≤0.03%, ensuring minimal interference in sensitive applications like HPLC and spectroscopy.

2. Can this acetonitrile be used for LC-MS applications?

Yes, its high purity and low UV cutoff make it suitable for LC-MS, though LC-MS-grade acetonitrile may offer even lower impurity profiles for ultra-sensitive mass spectrometry.

3. How should I store ACETONITRILE 99.5% AR to maintain its purity?

Store in a tightly sealed amber glass bottle at room temperature, away from direct sunlight, moisture, and ignition sources. Use within 12 months of opening for optimal performance.

4. Is this solvent compatible with plastic containers or tubing?

Acetonitrile can dissolve certain plastics like polystyrene or PVC. Use glass, PTFE, or HDPE containers and tubing for storage and handling.

5. What alternatives exist if I need a lower-water-content acetonitrile?

For applications requiring ≤0.01% water, consider HPLC-grade or LC-MS-grade acetonitrile, which undergo additional drying processes.
