541-69-5 Usage
Chemical Properties
white to slightly red crystalline powder
Uses
m-Phenylenediamine dihydrochloride is used in the synthesis of bis(thiazolidone) and bis(thiohydantoin) derivatives. It can be used to increase the pore size in the fabrication of poly(aniline-co-1,3-phenylenediamine) cryogels.
Safety Profile
Poison by intraperitoneal route. Questionable carcinogen with experimental tumorigenic data. Mutation data reported. When heated to decomposition it emits very toxic fumes of HCl and NOx. See also other phenylenediamine entries and AMINES
Check Digit Verification of cas no
The CAS Registry Mumber 541-69-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,4 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 541-69:
(5*5)+(4*4)+(3*1)+(2*6)+(1*9)=65
65 % 10 = 5
So 541-69-5 is a valid CAS Registry Number.

Reduction of dinitrobenzenes by electron-carrying catalysts in the electrosynthesis of diaminobenzenes

The interaction of isomeric dinitrobenzenes (DNBs) with titanium(III), tin(II), and vanadium(II) chlorides, which are reducing agents used as electron carriers in the electrosynthesis of diaminobenzenes, has been studied. Rate constants of the reduction of isomeric DNBs and nitrophenylhydroxylamines by SnCl2 and TiCl3 in a 2 M water-alcohol solution (10 vol.% C2H5OH) of HCl were measured, and activation energies of the reduction of isomeric DNBs were determined. The rates of interaction of DNBs with the listed mediators increase in the series SnCl2 3 2. It is shown that the electrolysis of DNBs in the presence of an excess of these mediators makes it possible to obtain the corresponding diaminobenzenes with a yield of 60–90%.
