quaternary ammonium compound
Noun: A quaternary ammonium compound is a type of chemical compound derived from ammonium ions in which all four hydrogen atoms are replaced by organic groups (alkyl or aryl groups). These compounds are typically cationic surfactants and are widely used for their antimicrobial properties, as well as in various industrial and pharmaceutical applications.
Quaternary ammonium compounds are primarily used as disinfectants, antiseptics, fabric softeners, and surfactants. They function by disrupting microbial cell membranes. - The hospital uses a quaternary ammonium compound to disinfect surfaces. - Quaternary ammonium compounds are common active ingredients in many household sanitizing wipes.
In specialized contexts, these compounds are referred to as "quats." They are valued for their stability and effectiveness against a broad spectrum of microorganisms. - The efficacy of the quaternary ammonium compound was tested against enveloped viruses. - Research focuses on novel quaternary ammonium compounds with reduced environmental persistence.
- Quat (n.): A common abbreviation for a quaternary ammonium compound.
- This cleaner contains a potent quat.
- Benzalkonium chloride (n.): A specific and common type of quaternary ammonium compound used as a disinfectant.
- Benzalkonium chloride is a quaternary ammonium compound found in many eye drops.
- Cationic surfactant (when referring to its surface-active property).
- Ammonium salt (in a broad, less specific chemical sense).
- QAC: An initialism for Quaternary Ammonium Compound.
- The safety data sheet lists the QAC concentration.
-
a compound derived from ammonium with hydrogen atoms replaced by organic groups; used as surface-active agents, disinfectants, and in drugs
