Acetonitrile (CAS 75-05-8) is a polar aprotic solvent supplied as a colorless liquid with an ethereal odor, valued for dissolving a wide range of organic and inorganic compounds and used in pharmaceutical synthesis, chromatography, and electronics manufacturing. We supply HPLC Grade and Technical Grade variants to meet specific analytical and manufacturing requirements.
This chemical is indispensable in the pharmaceutical industry for the synthesis of complex molecules and as a mobile phase in chromatography. It features a low viscosity and high dielectric constant, providing exceptional reaction kinetics in chemical processes.
In the electronics sector, its high stability makes it a preferred electrolyte solvent for high-energy batteries and capacitors. Our product is strictly filtered to ensure minimal UV absorbance and ultra-low water content for sensitive applications.

Acetonitrile
Applications
- Liquid Chromatography (HPLC): The primary solvent for analytical laboratories due to its high transparency and elution strength
- DNA/RNA Synthesis: Used as a specialized solvent and reagent medium in the production of oligonucleotides and genetic materials.
- Butadiene Extraction: Employed in petrochemical plants as a selective solvent for separating butadiene from other hydrocarbon streams.
Safety & Risks
Classified as a Highly Flammable Liquid and Acute Toxin. Metabolizes into cyanide in the body; strictly require chemical-resistant gloves, eye protection, and respiratory equipment.
