3056-93-7 Usage
Description
BASIC ORANGE 21 is a bright yellow orange dye that is soluble in water and ethanol, with a slight solubility in cold water and full solubility in hot water. It is known for its ability to dye acrylic fiber with a bright yellow orange color and to give a slant red light when used with a tungsten filament. The color remains unchanged at 120°C during dyeing, but it is sensitive to the presence of copper and iron ions, which can cause significant color changes.
Uses
Used in Textile Industry:
BASIC ORANGE 21 is used as a dye for acrylic, two vinegar fiber, and modified polyester in the textile industry. It provides a bright yellow orange color to the fibers, enhancing their visual appeal and making them more attractive to consumers.
Standard:
The light fastness, perspiration fastness, ironing fastness, and soaping of BASIC ORANGE 21 are rated as ISO 4-5 and AATCC 5-6, indicating that the dye has good resistance to various conditions, such as exposure to light, sweat, ironing, and washing. However, the fading and staining ratings are lower, with ISO ratings of 4-5 for fading and AATCC ratings of 3 for staining, suggesting that the dye may not be as resistant to these specific conditions.
Preparation
2-(1,3,3-Trimethylindolin-2-yl)acetaldehyde and 2-Methyl-2H-indazole??in 90 ℃ in the condensation, and then dumped into the water, and translated into chloride.

Check Digit Verification of cas no
The CAS Registry Mumber 3056-93-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,5 and 6 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3056-93:
(6*3)+(5*0)+(4*5)+(3*6)+(2*9)+(1*3)=77
77 % 10 = 7
So 3056-93-7 is a valid CAS Registry Number.
