Uses
Used in Pesticide Industry:
Phosphoramidothioic acid O-ethyl S-methyl ester is used as an active ingredient in various pesticide formulations for its potent insecticidal and acaricidal properties. It is applied to control pests in agricultural settings to protect crops from damage and increase yield.
Used in Insecticide Formulations:
In the insecticide industry, Phosphoramidothioic acid O-ethyl S-methyl ester serves as a key component in insecticide products, targeting a wide range of insects that can be detrimental to both agricultural and residential areas. Its use helps in managing infestations and preventing the spread of insect-borne diseases.
Used in Mite Control:
Phosphoramidothioic acid O-ethyl S-methyl ester is also utilized in the control of mites, which can be harmful to plants, animals, and humans. Its application helps in reducing mite populations and mitigating the damage they cause to crops and livestock.
Check Digit Verification of cas no
The CAS Registry Mumber 10265-93-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,2,6 and 5 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 10265-93:
(7*1)+(6*0)+(5*2)+(4*6)+(3*5)+(2*9)+(1*3)=77
77 % 10 = 7
So 10265-93-7 is a valid CAS Registry Number.

Chiral Mono-, Di, and Tri-chloromethylphosphonates and Phosphonothioates: Preparation, Absolute Configuration, and the Stereochemical Course of Their Reaction with Methoxide

Enantiomerically pure (+)-(R)-O-ethyl S-methyl dichloromethylphosphonothioate, prepared using (-)-ephedrine as a chiral template, is futher chlorinated to the trichloro analogue using BunLi-CCl4 and dechlorinated by hydrogenolysis via the monochloro analogue to the corresponding methyl-phosphonothioate of known configuration.With methoxide, the trichloro derivatives gives P-C bond cleavage with inversion and the dichloro derivatives gives P-S bond cleavages with retention of configuration.In the monochloroderivative P-S and P-O bond cleavages are competitive, P-S bond cleavage occuring with 70percent inversion.Under similar reaction conditions P-S bond cleavage occurs stereospecifically with inversion of configuration in methylphosphonothioates.Methoxide treatment of (+)-(R)-ethyl isopropyl trichloromethylphosphonate results in P-C bond cleavage with inversion while (-)-(S)-ethyl phenyl dichloromethylphosphonate loses the OPh group also with inversion.Possible reaction mechanisms are discussed.
