Overview

(2-hydroxyphenoxy)-phenylmercury (CAS 3688-11-7) is an organomercury compound with potent biocidal properties and extreme toxicity concerns. This organomercury compound represents a specialized chemical intermediate characterized by its phenylmercury moiety bonded to a hydroxyphenoxy group. With a molecular formula of C12H10HgO2 and molecular weight of 386.8 g/mol, this substance exhibits the typical properties associated with organomercury compounds, including high biological activity and significant environmental persistence. The compound carries severe safety classifications under the GHS system, including Acute Toxicity Categories 1 and 2, indicating fatal or toxic effects through multiple exposure routes. Its STOT RE 2 classification warns of potential organ damage through repeated exposure, while its Aquatic Acute 1 and Chronic 1 classifications highlight extreme aquatic toxicity. These hazard profiles are consistent with other mercury-containing compounds such as dimethylmercury, though the specific toxicity mechanisms may vary based on molecular structure. Safety handling requires strict protocols due to its ADR Class 6.1 classification as a toxic substance. The presence of GHS06, GHS08, and GHS09 pictograms emphasizes acute toxicity, health hazards, and environmental dangers respectively. Personal protective equipment, specialized ventilation systems, and mercury-specific waste disposal procedures are essential. Industrial applications typically involve specialized biocidal formulations and certain catalytic processes where the unique reactivity of the organomercury functionality provides specific advantages. Some applications may overlap with those historically served by mercury(2+) dithiocyanate before regulatory restrictions. OYSI maintains technical expertise in organometallic compounds and can provide guidance on proper handling, regulatory compliance, and application-specific requirements for this specialized chemical intermediate.
