1325-32-2 Usage
Uses
Used in Dye Industry:
Copper, diazotized 2-methoxy-4-nitrobenzenamine-4-[(8-hydroxy-6-sulfo-2-naphthalenyl)amino]benzoic acid coupling products complexes is used as a dye for its ability to produce dark to gray colors in water and violet black colors when reacted with strong hydrochloric acid solution. Its resistance to acids and alkalis, as well as its light fastness, make it a suitable choice for various dyeing applications.
Used in Textile Industry:
In the textile industry, Copper, diazotized 2-methoxy-4-nitrobenzenamine-4-[(8-hydroxy-6-sulfo-2-naphthalenyl)amino]benzoic acid coupling products complexes is used as a colorant for its strong staining properties and resistance to fading in water. Its acid and alkali resistance also contribute to its suitability for use in the textile industry.

Check Digit Verification of cas no
The CAS Registry Mumber 1325-32-2 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 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1325-32:
(6*1)+(5*3)+(4*2)+(3*5)+(2*3)+(1*2)=52
52 % 10 = 2
So 1325-32-2 is a valid CAS Registry Number.
