145017-98-7 Usage
Uses
Used in Textile Industry:
REACTIVE RED 198 is used as a dye for cotton fabric in the textile industry for the following reasons:
1. Exhaust dyeing method: REACTIVE RED 198 is utilized in the exhaust dyeing process, which involves applying the dye directly to the textile material and then fixing it through a series of treatments, such as heat and steam.
2. Pad dyeing method: This dye is also used in the pad dyeing process, where the fabric is passed through a solution containing the dye and then dried and cured to achieve the desired color.
Standard:
The performance standards for REACTIVE RED 198 in terms of light fastness, oxygen bleaching, perspiration fastness, and soaping are as follows:
Light Fastness: ISO 5
Oxygen Bleaching: ISO 5
Perspiration Fastness: ISO 4-5
Soaping: ISO 5
These standards indicate the dye's resistance to fading and staining under various conditions, ensuring its suitability for use in the textile industry.
Preparation
2-(4-Aminophenylsulfonyl)ethyl hydrogen sulfate diazo, and 4-Amino-5-hydroxynaphthalene-2,7-disulfonic acid?coupling, again with 2,4,6-Trichloro-1,3,5-triazine condensation, the last and the 3-Aminobenzenesulfonic acid condensation.

Check Digit Verification of cas no
The CAS Registry Mumber 145017-98-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,0,1 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 145017-98:
(8*1)+(7*4)+(6*5)+(5*0)+(4*1)+(3*7)+(2*9)+(1*8)=117
117 % 10 = 7
So 145017-98-7 is a valid CAS Registry Number.
