12236-84-9 Usage
Description
PROCION BLUE H-5R is a synthetic, reactive dye belonging to the azoic class, characterized by its dark blue color in the form of a powder. It is soluble in water and exhibits various color changes when exposed to different acids and alkalis. This dye is known for its use in the textile industry, particularly for dyeing and printing fabrics, and is also recognized as a water-soluble pollutant due to its environmental impact.
Uses
Used in Textile Industry:
PROCION BLUE H-5R is used as a dye for various types of fabrics, including cotton, viscose, wool, and silk. It is particularly suitable for continuous rolling processes, providing a vibrant blue color to the material. The dye is known for its light fastness, with an ISO rating of 6-7, and its resistance to oxygen bleaching and perspiration, making it a popular choice for long-lasting color in textiles.
In addition to its use in the textile industry, PROCION BLUE H-5R may also have potential applications in other industries, such as the paper and leather industries, where its color properties and solubility could be advantageous. However, it is important to consider the environmental impact of using this dye, as it is classified as a water-soluble pollutant. Further research and development may be necessary to explore alternative uses for PROCION BLUE H-5R while minimizing its environmental footprint.

Check Digit Verification of cas no
The CAS Registry Mumber 12236-84-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,3 and 6 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 12236-84:
(7*1)+(6*2)+(5*2)+(4*3)+(3*6)+(2*8)+(1*4)=79
79 % 10 = 9
So 12236-84-9 is a valid CAS Registry Number.
