39280-63-2 Usage
Description
Acid Red 337 is a synthetic dye characterized by its brilliant red color. It is commonly used in various industries due to its distinct properties, such as light fastness, soaping fastness, perspiration fastness, oxygen bleaching, and fastness to seawater. The dye has been assigned an ISO rating, which indicates its performance in different applications.
Uses
Used in Textile Industry:
Acid Red 337 is used as a colorant for dyeing and printing on polyamide materials. Its light fastness and perspiration fastness make it suitable for use in fabrics that are exposed to sunlight and sweat, ensuring that the color remains vibrant and resistant to fading.
Used in Plastics Industry:
Acid Red 337 is used as an additive in the plastics industry to impart a brilliant red color to various types of plastics. Its fastness to oxygen bleaching and seawater makes it an ideal choice for applications where the plastic may be exposed to these elements, such as in marine environments or outdoor settings.
Used in Cosmetics Industry:
Acid Red 337 is used as a colorant in the cosmetics industry, particularly in products that require a vibrant red hue. Its light fastness ensures that the color remains consistent and resistant to fading, even when exposed to sunlight or other environmental factors.
Used in Food Industry:
Acid Red 337 is used as a coloring agent in the food industry, adding a bright red color to various products such as candies, beverages, and confectionery items. Its fastness properties ensure that the color remains stable and does not fade during processing or storage.
Used in Analytical Chemistry:
Acid Red 337 is used as an indicator in analytical chemistry, particularly in acid-base titrations. Its distinct color change at different pH levels makes it a useful tool for determining the endpoint of a titration.

Check Digit Verification of cas no
The CAS Registry Mumber 39280-63-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,2,8 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 39280-63:
(7*3)+(6*9)+(5*2)+(4*8)+(3*0)+(2*6)+(1*3)=132
132 % 10 = 2
So 39280-63-2 is a valid CAS Registry Number.
