858128-33-3 Usage
Uses
Used in Pesticide Industry:
(4-methoxyphenyl)phosphonothioic O,O'-acid is used as a pesticide for its strong and effective weed-killing properties. It works by disrupting the enzymatic activity in target plants, leading to their eventual death.
Used in Herbicide Industry:
(4-methoxyphenyl)phosphonothioic O,O'-acid is used as a herbicide for controlling and eliminating unwanted plants in agricultural fields and other areas. Its strong weed-killing properties make it an effective solution for managing plant growth.
Note: Due to its potential toxicity and environmental impact, the use of (4-methoxyphenyl)phosphonothioic O,O'-acid is regulated in many countries. Additionally, proper safety precautions must be taken when handling and applying (4-methoxyphenyl)phosphonothioic O,O'-acid to minimize risks to human health and the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 858128-33-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,8,1,2 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 858128-33:
(8*8)+(7*5)+(6*8)+(5*1)+(4*2)+(3*8)+(2*3)+(1*3)=193
193 % 10 = 3
So 858128-33-3 is a valid CAS Registry Number.

Lawesson's reagent for direct thionation of hydroxamic acids: Substituent effects on LR reactivity
Przychodzen, Witold
, p. 676 - 684 (2007/10/03)
To explore the generality and scope of direct thionation of hydroxamic acids (HAs), the reaction of various structurally diverse HAs with Lawesson's reagent was investigated. The yield of thiohydroxamic acid (THAs) is poor when HAs possess bulky acyl and/or N-substituents, acidic α-hydrogen atoms, or an N-phenyl ring. THAs yields were correlated with Brown sigma parameter. The relative rates of two subsequent processes kT2 and kR2 were also measured. Correlation was also found for methine proton chemical shifts of N-isopropyl benzothiohydroxamic acids.
Mechanism of the reaction of lawesson's reagent with N-alkylhydroxamic acids
Przychodzen, Witold
, p. 2002 - 2014 (2007/10/03)
The mechanism of the reaction under discussion has been established by investigating the products of the reaction between 2,4-bis(4-methoxyphenyl)-1,3, 2,4-dithiadiphosphetane 2,4-disulfide (Lawesson's reagent, LR) and N-alkylhydroxamic acids HAs 1. The p
