Beschreibung

Anwendung

Benzethonium hydroxide solution has been used for the trapping of 14CO2. Benzethonium hydroxide is suitable to evaluate the kinetics of 14carbon dioxide (14CO2) excretion by oral commensal flora to theoretically propose optimum breath collection timings for 14C urea breath test.

Biochem./physiol. Wirkung

Benzethonium is a cationic of quaternary ammonium salt consisting of diisobutylphenoxyethoxyethyl dimethyl-benzyl ammonium compound. It possess antimicrobial and antiseptic functionalities. Benzethonium hydroxide conversion to carbamate in the presence of exhaled carbon dioxide results in colour change. Hence, it is used in carbon urea breath test.
