O,O-bis(2-chloroethyl) phenylphosphonothioate, also known as sarin, is a highly toxic organophosphorus compound that acts as a potent nerve agent. It is a colorless, odorless, and tasteless liquid, making it difficult to detect. Sarin is a G-series nerve agent, which was developed in Germany during World War II. It inhibits the enzyme acetylcholinesterase, leading to the accumulation of acetylcholine in the nervous system and causing overstimulation of muscles and glands. Exposure to sarin can result in symptoms such as difficulty breathing, muscle twitching, seizures, and even death. Due to its extreme toxicity and potential for use in chemical warfare, sarin is classified as a weapon of mass destruction and is regulated under various international treaties.

6344-04-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6344-04-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,4 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6344-04:
(6*6)+(5*3)+(4*4)+(3*4)+(2*0)+(1*4)=83
83 % 10 = 3
So 6344-04-3 is a valid CAS Registry Number.

Phenyl thiophosphinic acid diester (haloethyl) compound and preparation method thereof

-

Paragraph 0035, (2016/10/10)

The invention relates to a phenyl thiophosphinic acid diester (haloethyl) compound and a preparation method thereof. The structure of the compound is as shown in the formula in the specification, wherein X is C1 or Br. The preparation method comprises the following steps: reacting phenyl thiophosphinic acid dimethyl ester with haloalcohol in the presence of a catalyst or reacting phenyl thiophosphinic acid dihalide with ethylene oxide in an organic solvent, and carrying out purification treatment, so as to obtain light yellow viscous liquid, namely phenyl thiophosphinic acid diester (haloethyl). The series flame retardant phenyl thiophosphinic acid diester (haloethyl) provided by the invention contains three flame-retardant elements, namely phosphorus, sulfur and halogen, is good in synergistic flame-retardant effect, better in plasticization, and suitable for being used as a flame-retardant plasticizer for PVC, polyurethane, epoxy resin, unsaturated resin and other materials; the preparation method is simple in process, high in yield, free from hydrogen chloride pollution, less in equipment investment and easy for large-scale production.
