1327-79-3 Usage
Preparation
3-(4-Hydroxyanilino)carbazole in 107 ℃ in Butanol sodium polysulfide solution reflux heating 24 hours, and then with sodium nitrite short time heating, steam out of Butanol, through the air and add salt to make dye completely precipitated out. This indophenol is by carbazole and nitroso phenol in concentrated sulfuric acid in – 20 to 23 ℃ condensation, then reduction and have to (BIOS983, 71 -74). To cure solution is to add 3 – methyl – 4 ‘- hydroxy – 4 -aminodiphenylamine, 4, 4’ – dihydroxydiphenyl aniline and phenol , improved the performance of the dye (BIOS983, 75- 81). Note: use with C.I. leuco sulfur dye similar method, some the structure of the dyes can be converted into the leuco compound.
Properties and Applications
red light blue to red light navy blue. In concentrated sulfuric acid for the faint blue, blue precipitation after dilution.

Check Digit Verification of cas no
The CAS Registry Mumber 1327-79-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,2 and 7 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1327-79:
(6*1)+(5*3)+(4*2)+(3*7)+(2*7)+(1*9)=73
73 % 10 = 3
So 1327-79-3 is a valid CAS Registry Number.
