General Description

1,2-Benzenedisulfonic acid, 4-amino- is a sulfonic acid derivative of benzene with two sulfonic acid groups and an amino group attached to the benzene ring. It is typically used as a dye intermediate and in the production of azo dyes, which are commonly used in the textile and paper industries. This chemical is also used as a component in the synthesis of pharmaceuticals and as a catalyst in various chemical reactions. In addition, it is a potential source of environmental pollution and may pose health risks if not handled and disposed of properly. Overall, 1,2-Benzenedisulfonic acid, 4-amino- has important industrial applications but also requires careful handling and disposal to mitigate potential risks.

Check Digit Verification of cas no

The CAS Registry Mumber 23602-42-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,6,0 and 2 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 23602-42:
(7*2)+(6*3)+(5*6)+(4*0)+(3*2)+(2*4)+(1*2)=78
78 % 10 = 8
So 23602-42-8 is a valid CAS Registry Number.

Fiber-reactive disazo brown dye having vinylsulfone-type reactive group

-

, (2008/06/13)

A compound, or a salt thereof, represented by the following formula, STR1 wherein A is a substituted or unsubstituted phenylene or naphthylene group, B is STR2 in which R3 is a hydrogen atom or a lower alkyl, lower alkoxy, acylamino or ureido group, and R4 is a hydrogen atom or a lower alkyl or lower alkoxy group, R1 and R3 are independently a hydrogen atom or a substituted or unsubstituted lower alkyl group, X is a substituted or unsubstituted amino, lower alkoxy, substituted phenoxy or sulfo group, Y is --SO2 CH=CH2 or --SO2 CH2 CH2 Z, in which Z is a group capable of being split by the action of an alkali, and m is 2 or 3, which is useful for dyeing hydroxyl group- or amide group-containing fiber materials to give dyed products of a brown color having excellent fastness properties with good build-up property.
