Beschreibung

Anwendung

Benzethonium hydroxide solution has been used for the trapping of 14CO2.[1][2] 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.[3]

Biochem./physiol. Wirkung

Benzethonium is a cationic of quaternary ammonium salt consisting of diisobutylphenoxyethoxyethyl dimethyl-benzyl ammonium compound. It possess antimicrobial and antiseptic functionalities.[4] 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.[5]
