Overview

Sulfanyl-sulfanylidene-bis(2,4,4-trimethylpentyl)-lambda5-phosphane (CAS 107667-02-7) is an organophosphorus compound with sulfur-containing functional groups and branched alkyl chains. This specialized organophosphorus compound belongs to the lambda5-phosphane family, characterized by its unique molecular structure incorporating both sulfanyl and sulfanylidene groups attached to a central phosphorus atom. With a molecular formula of C16H35PS2 and molecular weight of 322.6 g/mol, this chemical exhibits distinct properties that make it valuable for specific industrial applications requiring phosphorus-sulfur chemistry. The compound presents significant safety considerations due to its hazard classification profile. It is classified as a flammable liquid (Category 3), acutely toxic through multiple exposure routes, and highly corrosive to skin. The presence of GHS pictograms including flame, skull and crossbones, corrosion, and environmental hazard symbols underscores the need for strict handling protocols. Its ADR classification as Class 6.1 (toxic substances) requires specialized transport and storage conditions. From a chemical perspective, this lambda5-phosphane compound shares certain reactive characteristics with other electrophilic species such as prop-2-enal, though its organophosphorus nature provides distinct reactivity patterns. The branched 2,4,4-trimethylpentyl substituents contribute to its solubility profile and steric properties, influencing its behavior in chemical processes. Primary industrial applications include specialized organic synthesis where phosphorus-sulfur bond formation is required, advanced materials chemistry, and as an intermediate in pharmaceutical or agrochemical manufacturing. The compound's unique structure makes it particularly suitable for applications requiring specific stereochemical control or where conventional organophosphorus reagents prove inadequate. OYSI maintains availability of this technical-grade organophosphorus compound for qualified industrial customers with appropriate handling capabilities.
