3443-93-4 Usage
Uses
Used in Textile Industry:
1-amino-4-(cyclohexylamino)-9,10-dihydro-9,10-dioxoanthracene-2-carboxamide is used as a dye for the textile industry. It provides brilliant blue color to fabrics and is known for its excellent fastness properties, such as:
Ironing Fastness: Rated 3-4 on the ISO scale, indicating that the color remains largely unchanged after ironing.
Light Fastness: Rated 7-8 on the ISO scale, meaning the color is highly resistant to fading under direct sunlight.
Perspiration Fastness: Rated 3-4 on the ISO scale, suggesting that the color is relatively stable when exposed to sweat.
Washing Fastness: Rated 3-4 on the ISO scale, indicating that the color is relatively stable after washing.
1-amino-4-(cyclohexylamino)-9,10-dihydro-9,10-dioxoanthracene-2-carboxamide's properties make it suitable for use in various textile applications, such as clothing, upholstery, and other fabric products, where colorfastness is essential.
Preparation
1-Amino-4-bromo-9,10-dioxo-9,10-dihydroanthracene-2-sulfonic acid and Cyclohexanamine?reaction, and translated into sodium salt, its product (C.I. Disperse Blue 62) and sodium cyaniding and Ammonium bicarbonate?pressure generated in the 1-Amino-4-bromo-9,10-dioxo-9,10-dihydroanthracene-2-sulfonic acid, then hydrolysis.

Check Digit Verification of cas no
The CAS Registry Mumber 3443-93-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,4 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3443-93:
(6*3)+(5*4)+(4*4)+(3*3)+(2*9)+(1*3)=84
84 % 10 = 4
So 3443-93-4 is a valid CAS Registry Number.
