Description
2-PHENYLAZO-4-METHYLPHENOL is an organic compound characterized by its green-yellow color. It exhibits properties such as being soluble in ethanol, acetone, and benzene, and has good light fastness and acid resistance. However, it has poor heat resistance and is hardly soluble in hot water. 2-PHENYLAZO-4-METHYLPHENOL's melting point is between 107-108°C. It changes color when exposed to concentrated sulfuric acid, hot concentrated hydrochloric acid, and sodium hydroxide in a 2% hot solution.
Uses
Used in Coatings Industry:
2-PHENYLAZO-4-METHYLPHENOL is used as a colorant for transparent lacquer, providing a green light yellow hue.
Used in Plastics Industry:
2-PHENYLAZO-4-METHYLPHENOL is used as a coloring agent for rubber, organic glass, celluloid, and plastic products, enhancing their visual appeal.
Used in Packaging Industry:
2-PHENYLAZO-4-METHYLPHENOL is used for coloring aluminum foil, adding an aesthetic touch to packaging materials.
2-PHENYLAZO-4-METHYLPHENOL's light fastness and acid resistance make it suitable for various applications where color stability is crucial. However, its poor heat resistance should be considered when selecting it for high-temperature applications.

Check Digit Verification of cas no
The CAS Registry Mumber 952-47-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,5 and 2 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 952-47:
(5*9)+(4*5)+(3*2)+(2*4)+(1*7)=86
86 % 10 = 6
So 952-47-6 is a valid CAS Registry Number.
