29918-57-8 Usage
General Description
AMMONIUM O,O-DIISOPROPYLTHIOPHOSPHATE is an organophosphate compound that is commonly used as a pesticide. It is a cholinesterase inhibitor, meaning that it disrupts the function of the enzyme that breaks down the neurotransmitter acetylcholine in the nervous system. This can lead to overstimulation of cholinergic receptors, resulting in symptoms such as muscle twitching, excessive salivation, and eventually respiratory failure. Due to its toxicity, AMMONIUM O,O-DIISOPROPYLTHIOPHOSPHATE is considered a highly hazardous chemical and must be handled with care and proper protective equipment. Additionally, its use as a pesticide is strictly regulated to minimize environmental and human health risks.
Check Digit Verification of cas no
The CAS Registry Mumber 29918-57-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,9,1 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 29918-57:
(7*2)+(6*9)+(5*9)+(4*1)+(3*8)+(2*5)+(1*7)=158
158 % 10 = 8
So 29918-57-8 is a valid CAS Registry Number.

SYNTHESIS AND TRIBOCHEMICAL BEHAVIOUR OF SOME MONOTHIOPHOSPHORIC ACID DERIVATIVES
Zinke, Horst,Schumacher, Rolf
, p. 315 - 322 (2007/10/02)
Diisopropylphosphite reacts, with sulphur and ammonia to form ammonium monothiophosphoric acid-diisopropylester which, by subsequent reaction with different monochloroacetic acid esters, yields the corresponding monothiophosphoric-acid-O,O-diisopropyl-S-carboalkoximethylesters.These compounds show different wear- and friction-reduction properties in lubricating oils.The tribochemical activity at higher temperatures increases with the chain length of the carboxylic ester group.Auger electron spectroscopy (AES) of the worn metal surface shows that the wear reducing properties correspond with the phosphorus content in the metal surface produced by tribofragmentation of the monothiophosphates.A possible explanation of this effect is discussed. Key words: Diisopropylphosphite; monothiophosphoric-acid-O,O-diisopropyl-S-carboalkoximethylesters; lubricating oils; Auger electron spectroscopy; wear; tribofragmentation.
