39143-71-0 Usage
Uses
Used in Agriculture:
1-butyl-3-(2,6-dimethylphenyl)urea is used as a herbicide for controlling the growth of grasses and broadleaf weeds in agricultural fields. It works by inhibiting the photosystem II complex in plant cells, disrupting the normal process of photosynthesis and leading to the death of unwanted vegetation.
Environmental Concerns:
1-butyl-3-(2,6-dimethylphenyl)urea is used with caution due to its potential to contaminate groundwater and pose risks to aquatic ecosystems. Its persistence in the environment raises concerns over its long-term impact on ecosystems and the need for responsible use in accordance with regulations to minimize its environmental footprint.
Check Digit Verification of cas no
The CAS Registry Mumber 39143-71-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,1,4 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 39143-71:
(7*3)+(6*9)+(5*1)+(4*4)+(3*3)+(2*7)+(1*1)=120
120 % 10 = 0
So 39143-71-0 is a valid CAS Registry Number.

Oxidation of mixtures of thioureas: Part XI - Oxidation of mixtures of 1-alkyl-3-arylthioureas and thiourea and study of steric influence around aryl groups on formation of 1,2,4-thiadiazolines

Hydrogen peroxide oxidation of a mixture of 1-alkyl-3-arylthiourea and thiourea in acidic alcoholic solution yields two isomeric 3-amino-1,2,4-thiadiazolines (VI and VII) via amidinothiourea.The rearrangement of the intermediate bis(formamidine)sulphide to the amidinothiourea derivative has been found to be governed by the steric effect.
