Acetonitrile, often abbreviated MeCN (methyl cyanide), is the chemical compound with the formula CH 3 CN and structure H 3 C−C≡N. This colourless liquid is the simplest organic nitrile ( hydrogen cyanide is a simpler nitrile, but the cyanide anion is not classed as organic ).
Typical nitrile ligands are acetonitrile, propionitrile, and benzonitrile.The structures of [Ru(NH 3) 5 (NCPh)] n+ have been determined for the 2+ and 3+ oxidation states. Upon oxidation the Ru-NH 3 distances contract and the Ru-NCPh distances elongate, consistent with amines serving as pure-sigma donor ligands and nitriles functioning as pi-acceptors.
The protein manufacturing cost remains high and there is a growing demand to develop cost efficient and rapid protein purification methods. Understanding of the different protein purification methods and optimizing the downstream processing are critical to minimize production costs while maintaining the quality of acceptable standards of homogeneity.

The market size is defined through the market volume and the market potential. The market volume exhibits the totality of all realized sales volume of a special market. The volume is therefore dependent on the quantity of consumers and their ordinary demand. Furthermore, the market volume is either measured in quantities or qualities.
Aminoacetonitrile is the organic compound with the formula H 2 N−CH 2 −C≡N.The compound is a colorless liquid. It is unstable at room temperature, owing to the incompatibility of the amine nucleophile and the nitrile electrophile.
Trichloroacetonitrile can be obtained by chlorination of acetonitrile on a zinc, copper and alkaline earth metal halide-impregnated activated carbon catalyst at 200–400 °C with a 54% yield. [ 3 ] The high temperatures required by this process favours the formation of byproducts, such as tetrachloromethane .
A concentration ratio (CR) is the sum of the percentage market shares of (a pre-specified number of) the largest firms in an industry. An n-firm concentration ratio is a common measure of market structure and shows the combined market share of the n largest firms in the market.
