Overview

Chloro(2-methoxyethyl)mercury (CAS 123-88-6) is an organomercury compound characterized by high toxicity and environmental persistence. This specialized organometallic compound represents a significant class of mercury-containing chemicals used in specific industrial applications where its unique chemical properties are essential. With the molecular formula C3H7ClHgO and a molecular weight of 295.13 g/mol, chloro(2-methoxyethyl)mercury combines the reactivity of organomercury chemistry with the functional properties of methoxyethyl substitution. The compound exhibits severe safety considerations, classified under multiple hazard categories including acute toxicity (Category 3), specific target organ toxicity for repeated exposure (Category 1), and severe skin corrosion (Category 1B). Its environmental impact is equally concerning, with classifications for both acute and chronic aquatic toxicity (Category 1). These properties necessitate stringent handling protocols and specialized containment measures during storage, transport, and application. Due to its organomercury structure, this compound shares chemical characteristics with related mercury compounds such as nitrooxy(phenyl)mercury and acetyloxy(phenyl)mercury, though each exhibits distinct reactivity profiles based on their specific substituents. The presence of the 2-methoxyethyl group provides unique solubility and reactivity characteristics that distinguish it from other organomercury derivatives. Primary industrial applications include use as a catalyst in specialized organic synthesis reactions, as a reagent in analytical chemistry procedures, and in certain pharmaceutical intermediate manufacturing processes where its specific reactivity profile is required. OYSI maintains availability of chloro(2-methoxyethyl)mercury for qualified industrial customers with appropriate handling capabilities and regulatory compliance requirements.
