Product Overview
ACETONITRILE 99.8% PRA is a high-purity solvent designed for demanding laboratory applications, particularly in high-performance liquid chromatography (HPLC) and liquid chromatography-mass spectrometry (LC-MS). This ultra-pure grade ensures minimal interference with analytical results, offering exceptionally low UV absorbance and negligible impurity levels. Its polar aprotic nature makes it a versatile solvent for organic synthesis, protein purification, and DNA/RNA extraction protocols. The solvent undergoes rigorous purification processes to eliminate water, acids, and other contaminants, guaranteeing consistent performance in sensitive analytical workflows. Its stability under a wide range of temperatures and compatibility with most lab-grade plastics and glassware further enhance its utility. Whether used as a mobile phase in chromatography or as a reaction medium in organic chemistry, this ACETONITRILE delivers reliable, reproducible results without compromising instrument integrity or sample purity.
FAQs
1. What is the water content in ACETONITRILE 99.8% PRA?
The water content is typically below 0.005% (50 ppm), ensuring minimal interference in moisture-sensitive applications.
2. Can this ACETONITRILE be used for UV-Vis spectroscopy?
Yes, its ultra-low UV absorbance (cutoff <190 nm) makes it suitable for UV-Vis spectroscopy and other optical measurements.
3. Is this solvent compatible with PTFE or polypropylene containers?
Yes, it is chemically compatible with PTFE, polypropylene, and borosilicate glass, but avoid prolonged storage in HDPE.
4. How should ACETONITRILE 99.8% PRA be stored for long-term use?
Store in a tightly sealed container under nitrogen or argon in a cool, dry place, away from ignition sources and direct sunlight.
5. What alternatives exist if ACETONITRILE is unavailable for HPLC?
Methanol (HPLC grade) or a mixture of water/acetonitrile can sometimes substitute, but method validation is required.
