Properties and stability
1. It is effective not only against Gram-positive bacteria, but also against Gram-negative bacteria and some molds. It has low toxicity, little skin irritation, no photosensitivity, and is relatively stable to heat.
Storage method
This product should be kept sealed, dry and protected from light.
Synthesis method
1. There are two industrial synthesis process routes, one is obtained by bromination of salicylanilide as raw material, and the other isProduced by the reaction of 3,5-bromosalicylic acid and p-bromoaniline.
Purpose
1. Used to make disinfectant soap (neutral soap contains 0.3~0.5% of this product), which can be used to prevent and treat skin diseases and medical disinfection and washing liquid. It can also be used as a preservative in cosmetics.
