2945-96-2 Usage
Uses
Used in Textile Industry:
Direct Grey D is used as a dye for cellulose fibers, such as cotton or viscose, due to its good dye absorption rate and maximum affinity in the temperature range of 40-80°C. It is not used for printing but can also be used for dyeing silk, PVA, polyamide fiber, and their blended fabrics.
Standard:
The performance standards of Direct Grey D in terms of acid resistance, alkali resistance, light fastness, soaping, water fading, and stain fading are as follows:
Acid Resistance: ISO 2, AATCC 5
Alkali Resistance: ISO 3-4, AATCC 3
Light Fastness: ISO 3, AATCC 3
Soaping: ISO 2, AATCC 3
Water Fading: ISO 2, AATCC 3
Stain Fading: ISO 2, AATCC 3
These standards indicate the dye's performance and resistance to various conditions, making it suitable for use in the textile industry.
Preparation
(a) 4-Nitrobenzenamine diazo, and 2-Amino-4-methylanisole coupling, again diazo, in alkaline conditions and 6-Amino-4-hydroxynaphthalene-2-sulfonic acid?coupling, and then will the nitro reduction for amino; (b) N-(4-aminophenyl)acetamide diazo, and 2-Amino-4-methylanisole close, then diazo, in alkaline conditions and 6-Amino-4-hydroxynaphthalene-2-sulfonic acid acid hydrolysis, then three amino acetylcholine.

Check Digit Verification of cas no
The CAS Registry Mumber 2945-96-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,4 and 5 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2945-96:
(6*2)+(5*9)+(4*4)+(3*5)+(2*9)+(1*6)=112
112 % 10 = 2
So 2945-96-2 is a valid CAS Registry Number.
