Description
METHOMYL-OXIME is a metabolite of Methomyl, which is a carbamate pesticide. It is characterized by its off-white to pale yellow solid appearance.
Uses
1. Used in Post-Mortem Analysis:
METHOMYL-OXIME is used as a metabolite in post-mortem samples for the detection and analysis of Methomyl, a carbamate pesticide. This application is crucial in forensic investigations and toxicology to determine the presence of the pesticide in deceased individuals and its potential role in the cause of death.
2. Used in Environmental and Agricultural Monitoring:
METHOMYL-OXIME is used as a metabolite in environmental and agricultural monitoring to assess the presence and levels of Methomyl pesticide in soil, water, and crops. This helps in understanding the potential impact of the pesticide on the environment and human health, as well as in ensuring compliance with regulatory standards for pesticide use.
3. Used in Toxicology Research:
METHOMYL-OXIME is used as a metabolite in toxicology research to study the effects of Methomyl on living organisms. This research is essential for understanding the mechanism of action, potential health risks, and the development of safer alternatives or mitigation strategies for the pesticide.
4. Used in Analytical Chemistry:
METHOMYL-OXIME is used as a compound in analytical chemistry for the development of methods and techniques to detect and quantify the presence of Methomyl and its metabolites in various samples. This is important for improving the accuracy and reliability of pesticide residue analysis in food, environmental, and biological samples.
Check Digit Verification of cas no
The CAS Registry Mumber 13749-94-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,7,4 and 9 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 13749-94:
(7*1)+(6*3)+(5*7)+(4*4)+(3*9)+(2*9)+(1*4)=125
125 % 10 = 5
So 13749-94-5 is a valid CAS Registry Number.

Preparation method of methomyl oxime
-
Paragraph 0037-0072, (2020/03/03)
The invention discloses a preparation method for methomyl oxime. The preparation method comprises the following steps: (1) respectively dissolving acetaldehyde oxime and chlorine gas in an organic solvent to obtain an organic solution of acetaldehyde oxime and an organic solution of chlorine gas, and dissolving sodium methyl mercaptide and sodium hydroxide in an organic solvent to obtain a mixed organic solution; (2) with the organic solution of acetaldehyde oxime and the organic solution of chlorine gas as raw materials, carrying out continuous feeding for a chlorination reaction; and (3) immediately subjecting a chlorinated mixed solution obtained by a chlorination reaction to a methylthio substitution reaction with the mixed organic solution, removing the solvent from a crude methomyl oxime product obtained by the reaction, and adding a small amount of water to wash the crude methomyl oxime product so as to obtain high-quality methomyl oxime. The method is controllable in reaction heat, small in by-product influence, short in time, capable of avoiding decomposition of chloroacetaldoxime, low in the amount of generated wastewater and free of wasterwater odor, and the obtained finished methomyl oxime is high in yield and quality.
