2537-62-4 Usage
General Description
N-[2-[(2-bromo-6-cyano-4-nitrophenyl)azo]-5-(diethylamino)phenyl]acetamide is a chemical compound known as a diazo dye, which is commonly used as a colorant in textiles and cosmetics. It has a molecular structure that includes a diazo group (N=N), a bromine atom, a cyano group, a nitro group, and an acetamide group. N-[2-[(2-bromo-6-cyano-4-nitrophenyl)azo]-5-(diethylamino)phenyl]acetamide is a bright red/orange color and is often used to dye textiles such as cotton and wool. It is also used in the production of colored cosmetics such as lipstick and nail polish. Due to its complex structure and potential for skin irritation, it is important to handle and use this chemical with caution and follow safety guidelines.
Check Digit Verification of cas no
The CAS Registry Mumber 2537-62-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,3 and 7 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2537-62:
(6*2)+(5*5)+(4*3)+(3*7)+(2*6)+(1*2)=84
84 % 10 = 4
So 2537-62-4 is a valid CAS Registry Number.

Diazotization method of wet nitroaniline
-
Paragraph 0032-0035, (2019/01/05)
The invention provides a diazotization method of wet nitroaniline, and relates to the field of dye synthesis. The diazotization method comprises following steps: step one, evenly stirring sulfuric acid (98%) and nitrosyl sulfuric acid (40%) in a diazotization reactor; and step two, adding wet nitroaniline into the diazotization reactor at a controlled temperature of -10 to 40 DEG C to obtain diazotization salts, wherein the mole ratio of sulfuric acid to nitrosyl sulfuric acid to diazotization component is 1.0-6: 1.02-1.1: 1. The quality of the provided wet dye is the same as that of a dry product, the diazotization component does not need to be dried, and the provided dye is energy saving and environmentally friendly.
