General Description
1,3,5-trichloro-2-nitrosobenzene is a chemical compound with the molecular formula C6H2NCl3O. It is a yellow crystalline solid that is soluble in organic solvents but insoluble in water. 1,3,5-trichloro-2-nitrosobenzene is often used as a reagent in organic synthesis, particularly in the preparation of dyes and pigments. It is also a precursor for the synthesis of pharmaceuticals and agrochemicals. However, 1,3,5-trichloro-2-nitrosobenzene is considered to be hazardous and toxic, with potential adverse effects on the environment and human health, and therefore, proper safety precautions should be followed when handling this compound.
Check Digit Verification of cas no
The CAS Registry Mumber 1196-13-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,9 and 6 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1196-13:
(6*1)+(5*1)+(4*9)+(3*6)+(2*1)+(1*3)=70
70 % 10 = 0
So 1196-13-0 is a valid CAS Registry Number.

Oxidation of Primary Aromatic Amines, Catalyzed by Tungsten Compounds

Treatment of o-nitroanilines and o-aminobenzoic acids with 30 percent hydrogen peroxide in the presence of Na2WO4 and H3PO4 results in selective formation of corresponding nitroso derivatives.In other cases, the products are azoxy compounds.Oxidation of anilines containing alkyl or alkoxy groups in the ortho and para positions with hydrogen peroxide in the presence of Na2WO4 and tetrabutylammonium bromide quantitatively yields corresponding nitrosobenzenes.The H2O2-Na2WO4-H3PO4 system in the presence of tetrabutylammonium bromide is proposed for preparation of nitroso derivatives from anilines containing electron-acceptor meta and para substituents.
