156-25-2 Usage
Uses
Used in Textile Industry:
4'-N,N-dimethylamino-1'-phenylazo-3-pyridine is used as a dye in the textile industry for its bright and long-lasting color properties. It is particularly favored for coloring fabrics, providing a vibrant pink hue that enhances the visual appeal of various garments and textiles.
Used in Plastics Industry:
In the plastics industry, 4'-N,N-dimethylamino-1'-phenylazo-3-pyridine is used as a colorant to impart a striking pink shade to plastic products. Its ability to maintain color vibrancy over time makes it suitable for manufacturing a wide range of plastic items, including toys, packaging materials, and decorative objects.
Used in Other Industries:
4'-N,N-dimethylamino-1'-phenylazo-3-pyridine is also utilized in other industries for coloring various materials. Its applications extend beyond textiles and plastics, finding use in coloring paper, paints, and coatings, as well as in the production of certain consumer goods that require a bright pink coloration.
Despite its potential hazards, Brilliant Pink continues to be widely used in the production of various consumer goods due to its attractive color properties. However, it is essential to take necessary precautions during handling and processing to minimize the risk of skin and eye irritation.
Check Digit Verification of cas no
The CAS Registry Mumber 156-25-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,5 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 156-25:
(5*1)+(4*5)+(3*6)+(2*2)+(1*5)=52
52 % 10 = 2
So 156-25-2 is a valid CAS Registry Number.
