Description
Trisodium 4-hydroxy-5-[[4-[[1-hydroxy-6-(phenylamino)-3-sulphonato-2-naphthyl]azo]-5-methoxy-2-methylphenyl]azo]naphthalene-2,7-disulphonate, also known as Direct Blue 67, is an organic sodium salt derived from the formal condensation of Durazol blue 4R (acid form) with three equivalents of sodium hydroxide. It is an organic azo dye characterized by its blue appearance and is commonly used with textile fibers.
Uses
Used in Textile Industry:
Trisodium 4-hydroxy-5-[[4-[[1-hydroxy-6-(phenylamino)-3-sulphonato-2-naphthyl]azo]-5-methoxy-2-methylphenyl]azo]naphthalene-2,7-disulphonate is used as a dye for textile fibers due to its strong tinting strength of 100-105%. This allows for the creation of vibrant and long-lasting colors in fabrics.
Properties and Applications:
Appearance: The dye has a blue color, which is its primary characteristic.
Lighting: It has a rating of 4, indicating good resistance to fading under light exposure.
Soaping: The dye has a rating of 4-5, suggesting it maintains its color well after soaping, making it suitable for washing.
Perspiring: It also has a rating of 4-5, which means it retains its color even when exposed to sweat, an important property for clothing.
Friction (Dry): The dye has a rating of 4-5, showing it is resistant to color fading due to dry friction.
Friction (Wet): It has a rating of 4, indicating it is less resistant to color fading when wet, which may require more care during washing.
Residue on 80 Mesh: The maximum residue allowed is 5.0%, ensuring the dye is well-dispersed and does not leave excess residue on the fabric.
Water Solubility: The maximum water solubility is 1.0%, which helps maintain the dye's stability in aqueous solutions.
Volatite at 105°C: The maximum volatilization allowed is 1.0%, indicating the dye is stable at high temperatures.
Tinting Strength: The tinting strength is 100-105%, which is a measure of the dye's ability to impart color to a substrate.
Weight Metal Total: The maximum weight of metal allowed is 50ppm, ensuring the dye is free from heavy metal contamination.

Check Digit Verification of cas no
The CAS Registry Mumber 3354-97-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,5 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3354-97:
(6*3)+(5*3)+(4*5)+(3*4)+(2*9)+(1*7)=90
90 % 10 = 0
So 3354-97-0 is a valid CAS Registry Number.
