Acid Red 249 Use and Manufacturing

Methods of Manufacturing

Using 5-chloro-2-phenoxyaniline and N-p-toluenesulfonyl H acid as raw materials, first diazotize the former and then couple with the latter to obtain the product. After salting out, filtering and drying, the finished product is obtained.

Uses

Used for dyeing silk, nylon and wool textiles
