Overview

(2,6-dichloro-4-methylphenoxy)-dimethoxy-sulfanylidene-lambda5-phosphane (CAS 57018-04-9) is an organophosphorus compound with distinctive chlorinated aromatic structure and potential sensitization properties. This specialized organophosphorus compound represents a unique chemical structure combining a dichlorinated methylphenoxy group with a dimethoxy-sulfanylidene-lambda5-phosphane moiety. The molecular formula C9H11Cl2O3PS reflects its complex architecture, incorporating chlorine, phosphorus, and sulfur heteroatoms within a molecular weight of 301.13 g/mol. The compound's EC number 260-515-3 confirms its regulatory recognition within European chemical commerce. From a safety perspective, this substance requires careful handling due to its classification as a skin sensitizer (Skin Sens. 1B) and its significant aquatic toxicity profile (Aquatic Acute 1; Aquatic Chronic 1). The GHS07 and GHS09 pictograms emphasize both health hazards and environmental concerns, while the "Warning" signal word indicates moderate but important safety considerations. Its ADR Class 9 classification as a miscellaneous dangerous substance necessitates specialized transport protocols. The compound's unique phosphorus-sulfur functionality distinguishes it from simpler organophosphorus derivatives like triphenyl phosphite, potentially offering specialized reactivity profiles in synthetic applications. Industrial applications typically involve its use as an intermediate in pharmaceutical synthesis, specialty polymer modification, and advanced materials chemistry where its specific electronic properties prove valuable. The chlorinated aromatic system provides enhanced stability and selectivity compared to non-halogenated analogs, making it particularly suitable for applications requiring controlled reactivity patterns. Environmental fate considerations are critical given its aquatic toxicity classification. OYSI maintains technical-grade supplies of (2,6-dichloro-4-methylphenoxy)-dimethoxy-sulfanylidene-lambda5-phosphane for qualified industrial customers across European markets.
