O,S-diethyl methylphosphonodithioate, commonly known as Demeton-S, is a potent organophosphate insecticide and acaricide characterized by its high toxicity to a range of pests. It functions by inhibiting the enzyme acetylcholinesterase, which results in the accumulation of acetylcholine in the nervous system of insects and mites, leading to paralysis and death. Despite its effectiveness, it poses significant risks to human health and the environment due to its high toxicity.

3347-31-7 Usage

Uses

Used in Agricultural Applications:
O,S-diethyl methylphosphonodithioate is used as an insecticide and acaricide for controlling various pests in agriculture. It is effective against a wide range of insects and mites that can cause significant damage to crops, thereby protecting yields and ensuring food security.
Used in Horticultural Applications:
In horticulture, O,S-diethyl methylphosphonodithioate is employed to manage pests that affect the growth and quality of ornamental plants and trees. Its use helps maintain the aesthetic appeal and health of horticultural products, contributing to the industry's economic viability.
Used in Domestic Settings:
O,S-diethyl methylphosphonodithioate is also utilized in domestic settings for the control of household pests such as cockroaches and mites. Its application helps create a cleaner and healthier living environment by reducing the presence of disease-carrying insects.
However, due to the high toxicity of O,S-diethyl methylphosphonodithioate, it is crucial to handle and apply this chemical with extreme caution. Adherence to safety protocols and regulations is essential to minimize the risk of exposure to humans, animals, and the environment. Alternative, less toxic pest control methods should be considered where possible to reduce the reliance on such hazardous substances.

Check Digit Verification of cas no

The CAS Registry Mumber 3347-31-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,4 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3347-31:
(6*3)+(5*3)+(4*4)+(3*7)+(2*3)+(1*1)=77
77 % 10 = 7
So 3347-31-7 is a valid CAS Registry Number.
