Overview

(2-hydroxyphenoxy)-phenylmercury (CAS 3688-11-7) is an organomercury compound with high toxicity and environmental persistence characteristics. This organomercury chemical substance represents a specialized compound within the family of phenylmercury derivatives, characterized by its unique molecular structure combining a phenylmercury moiety with a hydroxyphenoxy group. With a molecular formula of C12H10HgO2 and molecular weight of 386.8 g/mol, this compound exhibits significant biological activity and environmental concerns typical of mercury-containing organic molecules. The substance presents considerable safety challenges, classified under multiple acute toxicity categories and carrying the "Danger" signal word with GHS pictograms indicating toxicity (GHS06), health hazards (GHS08), and environmental dangers (GHS09). Its classification as STOT RE 2 indicates potential for causing damage to organs through prolonged or repeated exposure, while its Aquatic Acute 1 and Aquatic Chronic 1 classifications highlight severe environmental risks to aquatic ecosystems. Transportation falls under ADR Class 6.1, reflecting its toxic nature. Unlike simpler mercury compounds such as dimethylmercury, this phenoxy-substituted derivative offers specific reactivity patterns that make it valuable in certain industrial applications. The compound finds primary use in specialized chemical synthesis processes, particularly in pharmaceutical intermediate production and as a catalyst in specific organic transformations. Additionally, it serves applications in analytical chemistry as a reagent for specialized detection methods and in certain antimicrobial formulations where its mercury content provides biocidal properties. Given the stringent regulatory framework surrounding mercury compounds and their environmental impact, proper handling protocols and waste management procedures are essential for industrial users. OYSI provides this specialized organomercury compound to qualified industrial customers with comprehensive safety documentation and regulatory compliance support.
