212138-65-3 Usage
Uses
Due to the potential health and environmental risks associated with DDE, its use has been banned or heavily restricted in many countries. However, it is important to note the following applications and reasons for its use in the past:
Used in Pesticide Industry:
2,4-dichloro-1-(2,2-dibromovinyl)benzene was used as an active ingredient in the pesticide DDT for its insecticidal properties. It was employed to control pests and protect crops from damage, thereby increasing agricultural productivity.
Used in Public Health:
DDE, as a component of DDT, was used in public health initiatives to control the spread of vector-borne diseases such as malaria, typhus, and dengue fever. Its insecticidal properties helped in reducing the population of disease-carrying insects, thereby reducing the incidence of these diseases.
It is crucial to emphasize that the use of DDE and DDT has been significantly reduced or banned in many countries due to their harmful effects on the environment and human health. Alternative, safer, and more environmentally friendly pesticides and public health measures have been developed and implemented to address the issues that DDE and DDT were initially used to solve.
Check Digit Verification of cas no
The CAS Registry Mumber 212138-65-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,2,1,3 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 212138-65:
(8*2)+(7*1)+(6*2)+(5*1)+(4*3)+(3*8)+(2*6)+(1*5)=93
93 % 10 = 3
So 212138-65-3 is a valid CAS Registry Number.

A new and highly efficient vicinal thiosulfonylation of 1,1-dibromo-1-alkenes with thiosulfonates in the presence of cesium carbonate has been developed. The metal-free diheterofunctionalization is an operationally simple to access a wide range of (E)-1,2-thiosulfonylethenes (α-aryl-β-thioarylvinyl sulfones) in moderate to high yields with high levels of stereoselectivities. Further, scalable reactions have been demonstrated for this transformation, thus illustrating its efficiency and practicality. (Figure presented.).
