61951-86-8 Usage
Description
REACTIVE YELLOW 86 is a brilliant green yellow dye in powder form, with a water solubility of 30 g/L at 50°C. It exhibits yellow color in concentrated sulfuric acid, which turns pale yellow upon dilution. Similarly, it shows yellow color in concentrated nitric acid, which also turns pale yellow when diluted. The dye solution appears light yellow, and upon the addition of 1 mol of sodium hydroxide, it turns yellow. Further addition of insurance powder and heating results in a pale yellow color. The dye becomes colorless when sodium perborate is added.
Uses
Used in Textile Industry:
REACTIVE YELLOW 86 is used as a dye for cotton and viscose fiber yarns and fabrics in jig dyeing or disseminated methods. It is suitable for fast and chlorine-resistant fabrics and can also be used for direct printing on cotton or rayon fibers, as well as resist and discharge printing.
Standard:
The light fastness, oxygen bleaching, perspiration fastness, and soaping of REACTIVE YELLOW 86 are rated according to the ISO standard. The ratings are as follows:
Light Fastness: 2 (red)
Oxygen Bleaching: 5
Perspiration Fastness: 4 (green, brilliant)
Soaping: 5
Fading: 4
Stain: 5
These ratings indicate the performance and durability of REACTIVE YELLOW 86 in various conditions, making it a suitable choice for textile applications.

Check Digit Verification of cas no
The CAS Registry Mumber 61951-86-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,9,5 and 1 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 61951-86:
(7*6)+(6*1)+(5*9)+(4*5)+(3*1)+(2*8)+(1*6)=138
138 % 10 = 8
So 61951-86-8 is a valid CAS Registry Number.
