NINGBO INNO PHARMCHEM CO.,LTD. is proud to present Acetonitrile, a high-quality chemical compound recognized for its versatility and critical role across numerous industries. As the simplest organic nitrile, Acetonitrile, with its chemical formula CH3CN and CAS No. 75-05-8, is a transparent, colorless liquid characterized by a faint, distinct, and slightly sweet aroma. Its unique combination of properties makes it an indispensable solvent and raw material in various sophisticated applications.

Key Properties and Composition
Acetonitrile boasts a molecular weight of 41.05 g/mol and a density of approximately 0.786 g/cm³ at 25°C, making it less dense than water. It has a boiling point ranging from 81.3°C to 82.1°C and a melting point between -46°C and -44°C. A notable feature is its high dielectric constant, around 36.64 to 38.8, alongside a low viscosity and excellent UV transparency (UV cutoff at 190-195 nm). These attributes contribute significantly to its wide applicability, especially in analytical techniques. Acetonitrile is readily miscible with water and a broad spectrum of organic solvents, excluding saturated hydrocarbons, allowing for flexible use in diverse chemical processes.

Extensive Industrial Applications
The utility of Acetonitrile spans a wide range of sectors:

• Pharmaceutical Industry: It serves as a vital solvent in the synthesis and purification of various pharmaceuticals, including Vitamin B1, and as an intermediate for compounds like dichloro chrysanthemum acid methyl ester and sulfonylurea herbicides. Its low toxicity profile in small doses makes it suitable for these sensitive applications, including oligonucleotide synthesis from nucleoside phosphoramidites.
• Analytical Chemistry: Acetonitrile is a preferred mobile phase in High-Performance Liquid Chromatography (HPLC) and LC-Mass Spectrometry (LC-MS) due to its low viscosity, low UV cutoff, and low chemical reactivity. It enables precise separation and analysis of complex mixtures.
• Chemical Synthesis: As a medium-polarity aprotic solvent, it is extensively used in various organic synthesis reactions, offering an ideal medium for dissolving both ionic and nonpolar compounds. It acts as a versatile two-carbon building block for many useful chemicals.
• Extraction Processes: Acetonitrile is crucial in the purification of butadiene in refineries and the extraction of C4 fractions in the synthetic rubber industry. It also plays a significant role in extracting fatty acids from oils and in the QuEChERS method for pesticide residue analysis, offering high extraction efficiency and clean phase separation.
• Battery and Electrochemistry: Its relatively high dielectric constant and ability to dissolve electrolytes make it an excellent solvent for battery applications and cyclic voltammetry.
• Other Uses: Acetonitrile is employed in the manufacturing of photographic film, perfumes, and certain pesticides. It can also be utilized for cleaning and degreasing surfaces in various industrial settings.
