Beschreibung4-Chlororesorcinol is a relatively safe hair dye agent, exhibiting no embryotoxicity, reproductive toxicity, teratogenic effects, or carcinogenic effects. This ingredient is typically used at concentrations below 1% and is present in over 30 hair dye products. Furthermore, the CIR Expert Panel has concluded that the use of 4-Chlororesorcinol in current hair dye formulations is safe. Furthermore, it may serve as an analytical reagent, functioning as a coupling agent in oxidation coupling reactions to determine the p-aminophenol (p-Amp) content in paracetamol, as well as the concentration of benzocaine (BENZ) and its preparations (ear drops).

Verwenden4-Chlororesorcinol is a halogenated phenol that can be used as hair dye formulation. It can also be used in the synthesis of series of six coumarin compounds carrying halogen and trifluoromethyl, having antifungal activities.

Darstellung · 1 Eintrag

synthetische4-Chlororesorcinol is synthesized by reacting resorcinol with dichlorosulfuryl. Resorcinol and diethyl ether were mixed, heated to reflux with stirring, and dichlorosulfuryl was slowly added dropwise. The temperature was then raised to 60°C for 1 h. After recovery of ether, atmospheric distillation is carried out, the distillate is subjected to vacuum distillation again, and the 131°C (0.8-0.93kPa) or 160-164°C (4.0kPa) fractions are collected to obtain the finished 4-chlororesorcinol.
