2151-60-2 Usage
Description
AURAMINE G is an organic compound that exhibits greenish-yellow fluorescence under normal light and bright yellow fluorescence when dissolved in water. It is soluble in ethanol, producing a yellow solution. When exposed to strong sulfuric acid, AURAMINE G turns colorless, but upon dilution, it regains a pale yellow color.
Uses
Used in Textile Industry:
AURAMINE G is used as a dye for the textile industry due to its bright yellow color and fluorescence properties. It is particularly useful for silk, as it offers good light fastness, perspiration fastness, ironing fastness, and soaping properties. This makes it a suitable choice for creating vibrant and long-lasting colors in silk fabrics.
Used in Stain Removal:
AURAMINE G is also used in the development of stain removal products. Its ability to dissolve in water and interact with various materials makes it effective in removing stains from fabrics.
Used in Fading Prevention:
In addition to its use as a dye, AURAMINE G is utilized in the prevention of fabric fading. Its light fastness properties help maintain the vibrancy of colors in fabrics, ensuring that they do not fade easily over time.
Preparation
will be dissolved in 4-(4-(Dimethylamino)-3-methylbenzyl)-N,N,2-trimethylbenzenamine, join ammonium chloride and sodium chloride, ammonia gas flow in in 175 ℃ heat the mixture, in 80 ℃ with hot water extraction.

Check Digit Verification of cas no
The CAS Registry Mumber 2151-60-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,5 and 1 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2151-60:
(6*2)+(5*1)+(4*5)+(3*1)+(2*6)+(1*0)=52
52 % 10 = 2
So 2151-60-2 is a valid CAS Registry Number.
