Urea, N,N'-bis(4-methylphenyl)-N-nitroso-, also known as 4,4'-dimethyldiphenylurea-N-nitroso (DMPU-NNO), is an organic compound with the chemical formula C15H16N4O. It is a derivative of urea, featuring two 4-methylphenyl groups attached to the nitrogen atoms and a nitroso group (-N=O) on one of the nitrogen atoms. Urea, N,N'-bis(4-methylphenyl)-N-nitroso- is of interest in chemical research due to its potential applications in various fields, such as the synthesis of dyes, pharmaceuticals, and as a precursor in the production of certain polymers. DMPU-NNO is a white crystalline solid that is sensitive to light and heat, and it is typically handled under controlled conditions to maintain its stability.

84784-22-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 84784-22-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,7,8 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 84784-22:
(7*8)+(6*4)+(5*7)+(4*8)+(3*4)+(2*2)+(1*2)=165
165 % 10 = 5
So 84784-22-5 is a valid CAS Registry Number.

Direct Transformation of Arylamines to Aryl Halides via Sodium Nitrite and N-Halosuccinimide

Mukhopadhyay, Sushobhan,Batra, Sanjay

, p. 14622 - 14626 (2018/09/21)

A one-pot universal approach for transforming arylamines to aryl halides via reaction with sodium nitrite (NaNO2) and N-halosuccinimide (NXS) in DMF at room temperature under metal- and acid-free condition is described. This new protocol that is complementary to the Sandmeyer reaction, is suggested to involve the in situ generation of nitryl halide induce nitrosylation of aryl amine to form the diazo intermediate which is halogenated to furnish the aryl halide.
