Acetonitrile (CAS 75-05-8) is a fundamental organic chemical widely recognized for its utility as a solvent in numerous industrial and laboratory applications. This colorless liquid, with its characteristic sweetish odor, possesses a unique set of properties that make it indispensable for processes ranging from chemical synthesis to advanced analytical techniques. NINGBO INNO PHARMCHEM CO.,LTD., a prominent manufacturer and supplier in China, offers high-quality Acetonitrile, understanding its critical role in various sectors. By exploring its properties, one can better appreciate why purchasing Acetonitrile is a strategic choice for many businesses.

Key Physical and Chemical Properties of Acetonitrile

Acetonitrile is classified as a polar aprotic solvent. Its molecular structure, CH3CN, features a nitrile group (–C≡N) attached to a methyl group (CH3). This configuration results in a significant dipole moment, contributing to its polarity and its ability to dissolve a wide array of polar and non-polar compounds. Some of its most notable properties include:

  • Miscibility: Acetonitrile is miscible with water and most common organic solvents, such as ethanol, acetone, and ethyl acetate, but not with saturated hydrocarbons. This broad solubility profile makes it highly versatile.
  • Volatility: With a boiling point of approximately 82 °C, Acetonitrile is volatile, which is advantageous for solvent removal after reactions or purification steps.
  • UV Transparency: Its low UV absorbance, particularly at wavelengths above 200 nm, makes it an excellent solvent for High-Performance Liquid Chromatography (HPLC) and other spectroscopic analyses.
  • Dielectric Constant: Acetonitrile has a relatively high dielectric constant (around 38.8), contributing to its ability to dissolve ionic compounds and electrolytes.
  • Low Viscosity: This property facilitates efficient flow through analytical instruments and reaction vessels.

Diverse Applications of Acetonitrile

The unique combination of these properties leads to Acetonitrile's extensive use across various industries:

  • Organic Synthesis: It serves as a reaction solvent and a reactant in the synthesis of pharmaceuticals, agrochemicals, and fine chemicals.
  • Chromatography: Acetonitrile is a standard mobile phase component in HPLC and LC-MS, crucial for separation and analysis in research and quality control.
  • Extraction: It is used in extraction processes, such as separating fatty acids from oils or purifying butadiene in refineries.
  • Pharmaceutical Industry: Beyond synthesis, it's used in the manufacturing of vitamins and as a solvent for photographic film.
  • Electronics: It finds application in battery electrolytes and other electronic components.
