Description
DIMETHYLVINPHOS, also known as dimethoate, is an organophosphate insecticide that is moderately persistent in the environment. It exhibits contact and stomach action, making it effective in controlling various pests.
Uses
Used in Agriculture:
DIMETHYLVINPHOS is used as an insecticide for controlling stem borers and leaf rollers in rice crops. It is applied in the form of a dust formulation to effectively manage these pests and protect the crop yield.
Metabolism
The main
degradation route in mammals is O-demethylation to
desmethyl dimethylvinphos, which is hydrolyzed to 2,2,4-
trichloroacetophenone.
Toxicity evaluation
The acute oral LD50 for rats is
155–210 mg/kg. Inhalation LC50 (4 h) for male and
female rats is 970–1189 and >4900 mg/m3 air.
Check Digit Verification of cas no
The CAS Registry Mumber 71363-52-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,3,6 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 71363-52:
(7*7)+(6*1)+(5*3)+(4*6)+(3*3)+(2*5)+(1*2)=115
115 % 10 = 5
So 71363-52-5 is a valid CAS Registry Number.

The reactions of 2,6-dichlorophenacyl and 2,6-dichlorophenacylidene chlorides and bromides with trimethyl and triethyl phosphites have been investigated.The reactivity of 2,6-dichlorophenacylidene chloride and bromide towards trialkyl phosphites was compared with that of 2,4-dichlorophenacylidene chloride and bromide.The influence of methanol, acting as a model protic solvent, on the above mentioned processes has also benn investigated.The mechanism of Perkow reaction of sterically hindered α-haloketones with bulky substituents around the carbonyl center is discussed.
