Overview

[Amino(methylsulfanyl)phosphoryl]oxymethane (CAS 10265-92-6) is an organophosphorus compound with significant acute toxicity and environmental hazard properties. This chemical substance, also identified by EC number 233-606-0, belongs to the family of organophosphorus compounds characterized by a phosphorus atom bonded to both sulfur and nitrogen functional groups. With a molecular formula of C2H8NO2PS and molecular weight of 141.13 g/mol, this compound exhibits distinct chemical properties that make it valuable for specific industrial applications while requiring careful handling protocols. The substance presents considerable safety concerns, classified under multiple acute toxicity categories (Acute Tox. 2 and Acute Tox. 3) and as an aquatic acute hazard (Aquatic Acute 1). The GHS06 and GHS09 pictograms indicate both acute toxicity and environmental dangers, while the ADR class 6.1 designation confirms its classification as a toxic substance for transportation purposes. The "Danger" signal word emphasizes the need for strict safety protocols during handling, storage, and transportation. Similar to other toxic organophosphorus compounds, this substance requires specialized handling procedures comparable to those used with related chemicals such as N-methylaniline, which also carries significant toxicity warnings. The phosphoryl group structure contributes to its reactivity profile and biological activity. Primary industrial applications include use as an intermediate in pharmaceutical synthesis, as a reagent in specialized chemical manufacturing processes, and in certain agricultural chemical formulations. The compound's unique phosphorus-sulfur-nitrogen framework makes it particularly valuable for creating derivatives with specific biological or chemical properties. OYSI maintains reliable supply chains for this specialized chemical substance, ensuring consistent availability for qualified industrial customers requiring organophosphorus compounds.
