CAS Number:298-00-0
Molecular formula:C8H10NO5PS
Molecular Weight:263.21

Parathion methyl is synthesised via a two-step process similar to that of parathion ethyl. The first step involves the chlorination of dimethyl dithiophosphoric acid to produce dimethylthiophosphoryl chloride. This intermediate is then reacted with sodium 4-nitrophenolate, the sodium salt of 4-nitrophenol, to form parathion methyl. The reaction typically follows the Schrader synthesis method.

Yield:-

Reaction Conditions:

Schrader synthesis;

Steps:

6 Example 6. Detoxification and biodegradation of methylparathion (METHAPHOS) under the action of lysine and microorganisms.
A sample OF METHYLPARATHION (O, O-DIMETHYL-O-P- nitrophenylthiophosphate) was obtained by the Schrader method interacting O, O- dimethylchlorothiophosphate with sodium salt of p-nitrophenol and was isolated by crystallization. The 1H and 31P NMR spectra data and melting point 34-36°C corresponded to the literature data.
