19177-72-1 Usage
General Description
1-phenyl-3-(2,2,2-trichloro-1-hydroxyethyl)urea, also known as diuron, is a synthetic organic compound that belongs to the phenylurea herbicides group. It is widely used as a pre-emergent herbicide to control grasses and broadleaf weeds in various crops, including sugar cane, cotton, and fruit trees. Diuron works by inhibiting photosynthesis in targeted plants, disrupting their ability to produce energy from sunlight. It is classified as a low to moderate toxicity chemical and is generally considered safe for use when applied according to label instructions. However, it may pose risks to aquatic ecosystems and has been found to persist in the environment for an extended period, leading to potential concerns about bioaccumulation and long-term environmental impacts.
Check Digit Verification of cas no
The CAS Registry Mumber 19177-72-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,1,7 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 19177-72:
(7*1)+(6*9)+(5*1)+(4*7)+(3*7)+(2*7)+(1*2)=131
131 % 10 = 1
So 19177-72-1 is a valid CAS Registry Number.

INTRA VS INTERMOLECULAR AMIDOALKILATION OF AROMATICS
Ishai, D. Ben,Sataty, I.,Peled, N.,Goldshare, R.
, p. 439 - 450 (2007/10/02)
Three tipes of intramolecular amidoalkylation reactions of aromatics, two endotrigonal and one exotrigonal (I, II, III), leading to indolone, N-acylisoquinolines, isoquinolone and benzazepinone derivatives were studied.In the presence of external aromatic nucleophiles competing intermolecular amidoalkylations were observed (1->2, 13->14).The mechanism and the synthetic limitations of the three types of cyclization is discussed.
