The Uses of Cetylpyridinium chloride monohydrate

(1-Hexadecyl)pyridinium chloride monohydrate is used in a study to assess removal of emulsified oil from oily waste water and removal of emulsified food and mineral oils from waste water. And it is used for detergent-based extraction of membrane-associated enzymes such as alkaline phosphatase, and in extraction of chromium and palladium.

Definition

ChEBI: Cetylpyridinium chloride monohydrate is a hydrate. It contains a cetylpyridinium chloride.

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.]
