6359-74-6 Usage
Uses
Used in Textile Industry:
Sodium p-[(4,5-dihydro-3-methyl-5-oxo-1-phenyl-1H-pyrazol-4-yl)azo]benzenesulphonate is used as a dye for wool and silk dyeing. It provides good light fastness, soaping, perspiration fastness, and fastness to oxygen bleaching and seawater.
Used in Pigment Industry:
Sodium p-[(4,5-dihydro-3-methyl-5-oxo-1-phenyl-1H-pyrazol-4-yl)azo]benzenesulphonate is used as a heavy metal salt in the production of organic pigments. It offers good light fastness, making it suitable for various applications in the pigment industry.
Standard:
The light fastness of sodium p-[(4,5-dihydro-3-methyl-5-oxo-1-phenyl-1H-pyrazol-4-yl)azo]benzenesulphonate is rated as ISO 5-6, indicating its ability to resist fading under direct sunlight. Its soaping fastness is rated as 2-3, and its perspiration fastness, oxygen bleaching, and seawater fastness are rated as 1, which means it may fade or stain under these conditions.
Preparation
4-Aminobenzenesulfonic acid diazo, and 3-Methyl-1-phenyl-1H-pyrazol-5(4H)-one?coupling.

Check Digit Verification of cas no
The CAS Registry Mumber 6359-74-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,5 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6359-74:
(6*6)+(5*3)+(4*5)+(3*9)+(2*7)+(1*4)=116
116 % 10 = 6
So 6359-74-6 is a valid CAS Registry Number.
