731-92-0 Usage
General Description
2,4-Dinitro-6-phenylphenol, also known as DNPP, is a chemical compound with the molecular formula C12H8N2O5. It is a yellow crystalline solid that is widely used as a fungicide and antimicrobial agent in various industrial and commercial applications. DNPP is known for its high effectiveness in inhibiting the growth of bacteria and fungi, making it a valuable ingredient in the production of personal care products, paints, coatings, plastics, and wood preservatives. However, DNPP is also classified as a substance of very high concern by the European Chemicals Agency due to its potential toxic effects on human health and the environment. Exposure to DNPP has been linked to skin and eye irritation, respiratory issues, and harmful effects on aquatic organisms. As a result, there are strict regulations and guidelines in place for the handling, use, and disposal of DNPP to minimize its impact on human health and the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 731-92-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,3 and 1 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 731-92:
(5*7)+(4*3)+(3*1)+(2*9)+(1*2)=70
70 % 10 = 0
So 731-92-0 is a valid CAS Registry Number.

Visible-Light-Induced Radical Polynitration of Arylboronic Acids: Synthesis of Polynitrophenols
Zhang, Qi,Raveendra Babu, Kaki,Huang, Zhouliang,Song, Jinna,Bi, Xihe
, p. 2891 - 2896 (2018/06/20)
We report a visible light-assisted one-pot method for the synthesis of polynitrophenols through radical tandem hydroxylation and nitration of arylboronic acids by utilizing copper(II) nitrate tri-nitydrate as the nitro source. This method features mild conditions, a simple procedure, and good functional group tolerance. Compared to conventional methods, this work provides a straightforward approach for the polynitration of aromatic compounds.

Nitration of the bromophenols (4a) and (5a) give products of nitro-debromination.Reaction of 6-methyl-4-nitro-2-phenylphenol (5c) with nitrogen dioxide gives 2-hydroxy-2-phenylcyclohex-3-enones (8) and (9), and probably stereoisomers (10), (20), (21) and (22).The mode of formation of these compounds is discussed.X-ray crystal structure determinations are reported for compounds (8) and (9).
