81-10-7 Usage
Uses
Used in Textile Industry:
2-Amino-N-ethylbenzenesulfonanilide is used as a dyeing agent for imparting vibrant yellow hues to cotton and silk fabrics. Its colorfastness and compatibility with natural fibers make it a preferred choice in textile dyeing processes.
Used in Paper Industry:
In the paper industry, 2-Amino-N-ethylbenzenesulfonanilide serves as an optical brightener, enhancing the whiteness and visual appeal of paper products. Its ability to absorb ultraviolet light and emit blue fluorescence contributes to the overall brightness and aesthetic quality of paper.
Used in Plastics and Fibers:
2-Amino-N-ethylbenzenesulfonanilide is used as a component in the production of fluorescent whitening agents for plastics and fibers. Its inclusion in these materials results in a brighter and more visually appealing final product, enhancing their marketability.
Used in Consumer Products:
2-Amino-N-ethylbenzenesulfonanilide finds application in the manufacturing of various consumer products such as soaps, detergents, and cosmetics. Its color-enhancing properties contribute to the visual appeal and marketing of these products, making them more attractive to consumers.
Check Digit Verification of cas no
The CAS Registry Mumber 81-10-7 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 1 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81-10:
(4*8)+(3*1)+(2*1)+(1*0)=37
37 % 10 = 7
So 81-10-7 is a valid CAS Registry Number.

Conversion of o-Nitrothiophenols into o-Aminobenzenesulphonic Acids
Bamfield, Peter,Greenwood, David,Lotey, Harvinder,Stirling, Charles J. M.
, p. 691 - 696 (2007/10/02)
The mechanism of conversion of o-nitrothiophenols into o-aminobenzenesulphonic acids in aqueous dioxane has been investigated with particular reference to evidence for the rate-determining formation of a cyclic intermediate.This intermediate is susceptible to interception by both external and internal nucleophilic functions, and the sulphonic acid is shown by isotope labelling experiments to take two oxygen atoms from H2(18)O in the reaction mixture, under conditons in which neither starting materials nor products exchange with H2(18)O.A tentative pathway is advanced.
