Overview

Dimethoxy-(3-methyl-4-methylsulfanylphenoxy)-sulfanylidene-lambda5-phosphane (CAS 55-38-9) is an organophosphorus compound with dual methoxy and methylsulfanyl functional groups exhibiting significant toxicological properties. This organophosphorus compound represents a specialized chemical intermediate characterized by its complex molecular structure containing phosphorus, sulfur, and oxygen functional groups. With a molecular formula of C10H15O3PS2 and molecular weight of 278.3 g/mol, this substance demonstrates the sophisticated chemistry typical of lambda5-phosphane derivatives. The compound's structure incorporates both methoxy substituents and a methylsulfanylphenoxy moiety, contributing to its unique reactivity profile and application potential in industrial processes. The substance requires careful handling due to its significant safety profile, classified under multiple hazard categories including mutagenicity (Muta. 2), acute toxicity (Acute Tox. 3 and 4), and specific target organ toxicity with repeated exposure (STOT RE 1). The presence of GHS08, GHS06, and GHS09 pictograms indicates serious health hazards, acute toxicity, and environmental dangers respectively. Its ADR classification of 6.1 designates it as a toxic substance requiring specialized transport protocols. Unlike simpler aromatic compounds such as N-methylaniline, this phosphane derivative presents more complex toxicological considerations due to its organophosphorus nature. Primary industrial applications include use as a chemical intermediate in pharmaceutical synthesis, specialty polymer production, and advanced materials manufacturing. The compound's unique combination of functional groups makes it valuable in developing organophosphorus-based catalysts and as a building block for complex molecular architectures. OYSI maintains availability of this specialized organophosphorus compound through our European distribution network, supporting customers with technical documentation and regulatory compliance guidance.
