Description
Vat Yellow 2 is an organic compound with the appearance of an orange powder. It is characterized by its green light yellow color and is insoluble in water and ethanol. In alkaline conditions, the powder appears purple, while in acidic conditions, it takes on a dark orange hue. When treated with strong sulfuric acid, it turns yellow. Vat Yellow 2 is primarily used in the dyeing and printing of textiles, such as cotton, silk, sheets, and towels, as well as for monochrome printing. It is also suitable for dyeing and printing of blended fabrics like viscose, polyester/cotton, and PVA/cotton, and can be used for paper dyeing.
Uses
Used in Textile Industry:
Vat Yellow 2 is used as a dye for cotton, silk, sheets, and towels, providing a vibrant green light yellow color. It is also used for monochrome printing on these materials.
Used in Blended Fabrics:
Vat Yellow 2 is used as a dye for blended fabrics such as viscose, polyester/cotton, and PVA/cotton, offering a consistent and long-lasting color.
Used in Paper Industry:
Vat Yellow 2 is used as a dye for paper, imparting a green light yellow hue to the material.
Standard:
Vat Yellow 2 meets various industry standards for fastness, bleach resistance, and fading, ensuring its reliability and performance in different applications. The ISO and AATCC ratings for different properties are as follows:
Ironing Fastness: ISO 4, AATCC 5
Chlorine bleach: ISO 5, AATCC 5
Light Fastness: ISO 3-4, AATCC 4
Mercerized: Not applicable
Oxygen bleach: ISO 4-5, AATCC 4-5
Soaping: ISO 5, AATCC 5
Fading: Not applicable
Stain: Not applicable
These ratings indicate that Vat Yellow 2 is a high-quality dye with good resistance to various conditions, making it suitable for a wide range of applications in the textile and paper industries.

Check Digit Verification of cas no
The CAS Registry Mumber 129-09-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 129-09:
(5*1)+(4*2)+(3*9)+(2*0)+(1*9)=49
49 % 10 = 9
So 129-09-9 is a valid CAS Registry Number.
