1052-38-6 Usage
Description
BISMARCK BROWN Y is a bis(azo) compound that is 1,1'-(1,3-phenylene)bis(diazene) in which both azene hydrogens are replaced by 2,4-diaminophenyl groups. It is a metachromatic dye which stains acid mucins yellow and is also a constituent of Papanicolaou's EA solutions, used for cervical and other smears. Its dihydrochloride salt is also a biological dye known as Bismark brown Y. It is characterized by its yellow brown color and is soluble in ethanol, acetone, and benzene. It exhibits different color changes when interacting with concentrated sulfuric and nitric acids, and its dye aqueous solution does not change color when hydrochloric acid is added, but it forms an orange precipitation when 10% sodium hydroxide solution is added.
Uses
Used in Histopathology:

Its versatility in staining and solubility in various solvents make it a valuable tool in both laboratory and clinical settings.
Preparation
2 Moore’s Nitrous acid?treatment 3 Moore’s Benzene-1,3-diamine dihydrochloride (this product may be based on the double azo dyes as the main component of the mixture, and commodity dye is usually composed of dihydrochloride composition), and made free base.
Flammability and Explosibility
Nonflammable
Check Digit Verification of cas no
The CAS Registry Mumber 1052-38-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,5 and 2 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1052-38:
(6*1)+(5*0)+(4*5)+(3*2)+(2*3)+(1*8)=46
46 % 10 = 6
So 1052-38-6 is a valid CAS Registry Number.
