1326-51-8 Usage
Description
Sulphur Brown 10 is a red-brown powder that is insoluble in water but soluble in sodium sulfide solution for brown and slightly soluble in concentrated sulfuric acid. It is a dye that is primarily used for cotton, hemp, viscose, and vinylon/cotton blended fabric dyeing, and occasionally in leather and paper dyeing.
Uses
Used in Textile Industry:
Sulphur Brown 10 is used as a dye for cotton, hemp, viscose, and vinylon/cotton blended fabrics due to its ability to provide a brown color. It is favored for its moderate acid resistance, severe alkali resistance, and good light fastness.
Used in Leather Industry:
Sulphur Brown 10 is used as a dye for leather, providing a brown color and offering moderate acid resistance and severe alkali resistance.
Used in Paper Industry:
Sulphur Brown 10 is used as a dye for paper, offering a brown color with moderate acid resistance and severe alkali resistance.
Standard:
The standard for Sulphur Brown 10 includes the following ratings:
Acid Resistance: Moderate (ISO 3, AATCC 3-4)
Alkali Resistance: Severe (ISO 4, AATCC 5)
Light Fastness: 3-4 (ISO, AATCC)
Fulling: 4 (ISO, AATCC)
Perspiration Fastness: 4 (ISO, AATCC)

Check Digit Verification of cas no
The CAS Registry Mumber 1326-51-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,2 and 6 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1326-51:
(6*1)+(5*3)+(4*2)+(3*6)+(2*5)+(1*1)=58
58 % 10 = 8
So 1326-51-8 is a valid CAS Registry Number.
