Cetylpyridinum chloride is a quaternary ammonium compound and an active ingredient of antiseptic oral mouth rinses with broad spectrum antimicrobial activity. Its mode of action involves a rapid bactericidal effect on Gram-positive pathogens and a fungicide effect on certain yeasts. Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
