Storage method
This product should be sealed and stored in a cool, dry place away from light.
Synthesis method
It is derived from the condensation of aniline and peri-acid in the presence of sulfuric acid. The condensation reaction product can be distilled under reduced pressure to obtain refined N-phenyl peri-acid. React it with soda ash, steam distill it, and decolorize it with activated carbon to obtain N-phenyl peri-acid.
Purpose
Fluorescent detector for protein research. Azo dye intermediates. Used in the production of acid dyes navy blue R, weak acid black BR, weak acid dark blue 5R, GR, and sulfide brilliant green 7B, etc.
