6359-55-3 Usage
Uses
Used in Textile Industry:
Sodium 5-chloro-4-[4-[(2-chlorophenyl)azo]-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl]toluene-3-sulphonate is used as a dye for wool and silk in the textile industry. It is known for its direct application in dyeing and printing processes, providing a vibrant yellow color to the fabrics.
sodium 5-chloro-4-[4-[(2-chlorophenyl)azo]-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl]toluene-3-sulphonate exhibits good light fastness (ISO 6), which means it maintains its color even when exposed to sunlight for extended periods. It also has a moderate soaping fastness (ISO 2), indicating that the color remains relatively stable when washed with soap. Additionally, it has a fair perspiration fastness (ISO 3), meaning the color does not easily fade when exposed to sweat.
However, it has a lower oxygen bleaching fastness (ISO 2-3) and a fading fastness to seawater (ISO 1-2), which suggests that the color may not be as stable when exposed to bleach or seawater. Despite these limitations, it is still a valuable dye for specific applications in the textile industry.

Check Digit Verification of cas no
The CAS Registry Mumber 6359-55-3 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, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 6359-55:
(6*6)+(5*3)+(4*5)+(3*9)+(2*5)+(1*5)=113
113 % 10 = 3
So 6359-55-3 is a valid CAS Registry Number.
