Dimethyl 4-(methylthio)phenyl phosphate

Dimethyl 4-(methylthio)phenyl phosphate

Dimethyl 4-(methylthio)phenyl phosphate is a chemical compound with the molecular formula C9H13O4PS. It is a derivative of phosphoric acid and is characterized by the presence of a methylthio group attached to a phenyl ring.

Chemical Structure

The chemical structure of Dimethyl 4-(methylthio)phenyl phosphate consists of a phenyl ring, which is a cyclic group of six carbon atoms bonded together in a hexagonal arrangement. Attached to the fourth carbon atom of the phenyl ring is a methylthio group, which consists of a methyl group (CH3) bonded to a sulfur atom. The sulfur atom is then bonded to the phosphorus atom of the phosphate group. The phosphate group is bonded to two methyl groups and an oxygen atom.

Synthesis

The synthesis of Dimethyl 4-(methylthio)phenyl phosphate typically involves the reaction of 4-(methylthio)phenol with dimethyl chlorophosphate in the presence of a base such as triethylamine. The reaction proceeds via a nucleophilic substitution mechanism, with the phenol acting as the nucleophile and the chlorophosphate acting as the electrophile.

Properties and Uses

Dimethyl 4-(methylthio)phenyl phosphate is a colorless to pale yellow liquid. It is used in the synthesis of various pharmaceuticals and agrochemicals. It is also used as a flame retardant in certain types of plastics.

Safety

Like many organophosphates, Dimethyl 4-(methylthio)phenyl phosphate is toxic and should be handled with care. It can cause irritation to the skin and eyes, and if ingested or inhaled, can cause serious health effects.
