2829-42-7 Usage
Description
Direct Fast Yellow 5GL is an organic dye that is characterized by its yellow appearance. It has a high tinting strength of 100-105%, indicating its ability to provide a strong coloration effect. The dye also has properties such as lighting, soaping, perspiring, and friction (both dry and wet), which are important for its performance in various applications. Additionally, it has a maximum residue on 80 mesh of 5.0%, a maximum water solubility of 1.0%, and a maximum volatile content at 105°C of 1.0%. The total weight metal content is also limited to a maximum of 50ppm.
Uses
Used in Textile Industry:
Direct Fast Yellow 5GL is used as a colorant for cellulosic fibers in the textile industry. Its high tinting strength and properties such as lighting, soaping, and friction make it suitable for dyeing and printing applications.
Used in Pharmaceutical Industry:
Direct Fast Yellow 5GL also displays inhibition properties towards the binding of HIV rgp120 to CD4. This suggests its potential use in the pharmaceutical industry as a compound for developing anti-HIV drugs or therapies.

Check Digit Verification of cas no
The CAS Registry Mumber 2829-42-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,2 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2829-42:
(6*2)+(5*8)+(4*2)+(3*9)+(2*4)+(1*2)=97
97 % 10 = 7
So 2829-42-7 is a valid CAS Registry Number.
