12262-37-2 Usage
Preparation
8-Amino-7-methylphenazin-2-ol?and sodium polysulphide?aqueous solution in return in 115 ~ 116 ℃ heating 30 hours, then dilution, through the air and add salt to the precipitation. This is Pyridine by 4-Methylbenzene-1,3-diamine?and 4-Aminophenol or 4-Nitrosophenol generated Indophenol?oxidation and become.Properties and Applications
bordeaux. Puce powder. Part of the soluble in water. In the sodium sulfide solution solubility is good, for the red light brown to brown; In concentrated sulfuric acid for dark blue purple, dilution after brown precipitation. Mainly used for cotton, hemp, viscose and vinylon/cotton blended fabric dyeing, suitable for dye corduroy, also used in leather dyeing.

4-5Check Digit Verification of cas no
The CAS Registry Mumber 12262-37-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,6 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.Calculate Digit Verification of CAS Registry Number 12262-37:
(7*1)+(6*2)+(5*2)+(4*6)+(3*2)+(2*3)+(1*7)=72
72 % 10 = 2
So 12262-37-2 is a valid CAS Registry Number.
