PRODUCT INTRODUCTION

description

4-Nitrotoluene-2-sulfonic acid is an important intermediate for the production of fluorescent whitening agents. It is used principally as starting material for the production of 4,4'-dinitrostilbene-2,2'-disulfonic acid, which in turn is used for the manufacture of a host of fluorescent whitening agents, based on cyanuric chloride, of the 4,4'-bis([1,3,5-triazin-2-yl]amino)-stilbene-2,2'-disulfonic acid type.
