General Description
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.
Purification Methods
Crystallise the chloride from MeOH or EtOH/diethyl ether and dry it in vacuo. [Moss et al. J Am Chem Soc 108 788 1986, Lennox & McClelland J Am Chem Soc 108 3771 1986, Beilstein 20 V 233.]
Toxics Screening Level
The initial threshold screening level (ITSL) for cetylpyridinium chloride monohydrate is 1.8 μg/m3 based on an annual averaging time.
