4444-48-8 Usage
Description
Naphthol AS-KN is a light yellow powder that is primarily utilized in the dyeing industry. It is known for its high affinity for cotton, making it an ideal choice for dyeing cotton yarns, cotton fabric, and viscose fiber. However, it is generally not used for printing due to its limited ability in this application.
Uses
Used in Textile Industry:
Naphthol AS-KN is used as a dyeing agent for cotton yarns, cotton fabric, and viscose fiber due to its high affinity for cotton. This property makes it a preferred choice for dyeing these materials, resulting in vibrant and long-lasting colors.
Used in Infrared Masking Color:
In addition to its dyeing applications, Naphthol AS-KN is also used in the production of infrared masking color. This application takes advantage of its light yellow hue, which can help in creating colors that are less visible or detectable in the infrared spectrum.
Preparation
3-Hydroxy-2-carboxydibenzofuran and Naphthalen-1-amine in chlorobenzene (including 5% DMF) were used in chlorinated and condensation.
Check Digit Verification of cas no
The CAS Registry Mumber 4444-48-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,4 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4444-48:
(6*4)+(5*4)+(4*4)+(3*4)+(2*4)+(1*8)=88
88 % 10 = 8
So 4444-48-8 is a valid CAS Registry Number.
