4-Nitro-2-sulfobenzoic acid(CAS#22952-26-7)

Introduction

It has good solubility in water and poor solubility in organic solvents. 2-Carboxy-5-nitrobenzene sulfonic acid is mainly used in the production of organic synthesis intermediates and dyes, and can also be used as a chemical reagent. The method of preparing 2-carboxy-5-nitrobenzene sulfonic acid is generally synthesized by nitrification reaction, first on the basis of p-nitrophenol substitution reaction to obtain 2-nitro-5-chlorophenol, and then nitrification reaction with nitrosulfuric acid to obtain the target product. It should be kept away from fire and high temperature environment, and stored in a dry and ventilated place.
