None

Synthesis method

Prepared from the reaction of phosphorus thiol benzoic acid and ethylmercuric chloride

Purpose

is a disinfectant and antiseptic. It has antibacterial and antimycobacterial effects and is more effective than mercurochrome. It is weaker than mercury chloride, less toxic and irritating. For external use as a skin and mucous membrane disinfectant. (Used for skin wound disinfection, eye and nose mucosal inflammation, urethral lavage, and skin fungal infections.)
