O,O-diethyl diethylphosphoramidothioate, also known as O,O-diethyl phosphorodithioate or malathion, is an organophosphorus compound widely used as an insecticide. It is a colorless, oily liquid with the chemical formula C10H19O5PS2. Malathion works by inhibiting the enzyme acetylcholinesterase in insects, leading to a buildup of acetylcholine and causing paralysis and death. It is effective against a broad range of pests, including aphids, mites, and mosquitoes, and is used in agriculture, horticulture, and public health. Malathion is considered less toxic to mammals than many other organophosphorus insecticides, but it can still pose risks to human health and the environment if not used properly.

5851-18-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5851-18-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,5 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5851-18:
(6*5)+(5*8)+(4*5)+(3*1)+(2*1)+(1*8)=103
103 % 10 = 3
So 5851-18-3 is a valid CAS Registry Number.

THE ISOMERIZATION/CHLORINATION OF O,O-DIALKYL N,N-DIALKYL THIOPHOSPHORAMIDATE WITH PHOSPHORUS OXYCHLORIDE - A NEW METHOD FOR SYNTHESIS OF S-ALKYL N,N-DIALKYL THIOPHOSPHORAMIDIC ACID DERIVATIVES

Tang, Chu Chi,Wu, Gui Ping,He, Shui Ji,He, Zheng Jie

, p. 91 - 94 (2007/10/02)

A new convenient method for synthesis of S-alkyl N,N-dialkyl thiophosphoramidic acid derivatives is reported.The chlorination of O,O-dialkyl N,N-dialkyl thiophosphoramidates with phosphorus oxychloride proceeds with isomerization to give S-alkyl N,N-dialk

REACTIONS OF α-MERCAPTOKETONES WITH P(III) AMIDES

Burilov, A.R.,Nikolaeva, I.L.,Pudovik, M.A.

, p. 691 - 693 (2007/10/02)

α-Mercaptoketones react with P(III) amides in two directions, depending on the experimental conditions and environment of the phosphorus atom: the first yields 1,3,2-oxathiaphospholenes and open-chain dithiophosphates and the second involves sulfurization of the initial P(III) amide under the action of α-mercaptoketones.

SYNTHESIS AND PROPERTIES OF β-FUNCTIONALIZED VINYL PHOSPHITES

Burilov, A. R.,Nikolaeva, I. L.,Pudovik, M. A.

, p. 542 - 545 (2007/10/02)

By phosphorylating (acylthio)acetones with dialkyl phosphorochloridites, the corresponding vinyl phosphites were synthesized and some their properties, e.g., sulfonation and reactions with chloral and acyl halides, were studied. (Acylthio)acetones react w
