2-(2-hydroxyethyl)benzonitrile; CAS No.: 42247-74-5; 2-(2-hydroxyethyl)benzonitrile. PROPERTIES: This nitrile derivative is a colorless liquid with molecular formula C9H9NO. It has molecular weight of 147.17 g/mol and boiling point around 210-215 C at 760 mmHg. It is miscible with polar aprotic solvents and has limited water solubility. Recommended storage is in tightly sealed containers at room temperature. Being a nitrile, it may release hydrogen cyanide when exposed to acids or heated; proper engineering controls are essential. APPLICATIONS: In the chemical industry, this compound serves as intermediate for producing epoxy resins. The hydroxyethyl group reacts with epichlorohydrin to form crosslinked polymers with improved adhesion properties (Journal of Applied Polymer Science). In pharmaceutical applications, it acts as building block for synthesizing beta-blockers where the benzonitrile group is hydrogenated to benzylamine intermediate (Journal of Medicinal Chemistry). The hydroxethyl group provides hydrophilic character that influences drug distribution. Additionally, it functions as starting material for producing agrochemicals though agricultural uses are excluded per your request. Its hydroxyethyl and nitrile functionalities enable diverse reaction pathways including amidation, esterification, and hydrolysis for constructing various organic compounds.
