6374-03-4 Usage
Uses
Used in Textile Industry:
2-[[4-[(2-Bromo-4,6-dinitrophenyl)azo]-3-methylphenyl]butylamino]ethanol is used as a dye for textiles due to its colorfastness properties. It provides good ironing fastness, light fastness, perspiration fastness, and washing fastness, ensuring that the color remains vibrant and resistant to fading and staining.
Used in Standard (Vinegar Fiber):
2-[[4-[(2-Bromo-4,6-dinitrophenyl)azo]-3-methylphenyl]butylamino]ethanol is used as a dye for vinegar fiber, a type of regenerated cellulose fiber. Its fastness properties make it an ideal choice for this application, ensuring that the color remains stable and resistant to fading and staining.

Check Digit Verification of cas no
The CAS Registry Mumber 6374-03-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,7 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6374-03:
(6*6)+(5*3)+(4*7)+(3*4)+(2*0)+(1*3)=94
94 % 10 = 4
So 6374-03-4 is a valid CAS Registry Number.
