32517-36-5 Usage
Description
Solvent Black 34 is a deep yellow powder that is slightly soluble in water and soluble in various organic solvents such as ethylene glycol ether, DMF, and ethanol. Its solution appears brown, and it exhibits slight changes in color when exposed to copper and iron ions.
Uses
Used in Textile Industry:
Solvent Black 34 is used as a dye for wool and polyamide fibers, as well as for directly printing on nylon fabric. It is particularly suitable for the finishing of natural leather, such as pigskin, cow leather, and goat leather, in the form of spray or curtains, especially for aniline leather spraying shading.
Standard (Perlon):
Solvent Black 34 has been tested for various fastness properties, including light fastness, soaping, perspiration fastness, oxygen bleaching, and fastness to seawater. The ISO ratings for these properties are as follows:
Light Fastness: ISO 7
Soaping: ISO 5
Perspiration Fastness: ISO 4-5
Oxygen Bleaching: ISO 5
Fastness to Seawater: ISO 3-4
These ratings indicate the performance and durability of Solvent Black 34 in various conditions, making it a versatile and reliable dye for different applications in the textile and leather industries.
Preparation
2-Amino-5-nitrophenol diazo, and Naphthalen-2-ol coupling, and then into a chrome complex (1 to 2 Moore single atoms chromium azo dyes).

Check Digit Verification of cas no
The CAS Registry Mumber 32517-36-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,5,1 and 7 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 32517-36:
(7*3)+(6*2)+(5*5)+(4*1)+(3*7)+(2*3)+(1*6)=95
95 % 10 = 5
So 32517-36-5 is a valid CAS Registry Number.
