Overview

2-chloroacetonitrile (CAS 107-14-2) is an organochlorine nitrile compound characterized by high toxicity and significant environmental persistence. This halogenated acetonitrile derivative represents an important building block in organic synthesis and industrial chemistry. The compound features a chlorine atom attached to the methyl carbon of acetonitrile, creating a reactive electrophilic center that makes it valuable for various chemical transformations. With its molecular formula C2H2ClN and molecular weight of 75.5 g/mol, 2-chloroacetonitrile exhibits distinct chemical properties that differentiate it from other halogenated nitriles such as 2,2,2-trichloroacetonitrile, which contains three chlorine atoms and demonstrates different reactivity patterns. The substance is classified under multiple acute toxicity categories (Acute Tox. 3) for oral, dermal, and inhalation exposure routes, requiring strict safety protocols during handling and storage. Its GHS06 skull and crossbones pictogram indicates fatal toxicity risks, while the GHS09 environmental pictogram reflects its classification as Aquatic Chronic 2, signaling long-term aquatic toxicity concerns. Transportation falls under ADR Class 6.1 for toxic substances, necessitating specialized logistics considerations. Primary industrial applications include its use as an intermediate in pharmaceutical synthesis, particularly in the production of heterocyclic compounds, and as a reagent in agrochemical manufacturing. The compound also serves as a precursor for various specialty chemicals and finds application in research laboratories for organic synthesis reactions where selective chloromethylation is required. OYSI provides reliable access to 2-chloroacetonitrile for European industrial customers, ensuring compliance with regional safety and environmental regulations.
