Quaternary ammonium cation. The R groups may be the same or different alkyl or aryl groups. Also, the R groups may be connected. In organic chemistry, quaternary ammonium cations, also known as quats, are positively-charged polyatomic ions of the structure [NR 4] +, where R is an alkyl group, an aryl group [1] or organyl group.
Dimethyldioctadecylammonium chloride (also commonly distearyl dimethyl ammonium chloride or distearyldimonium chloride) is an organic compound classified as quaternary ammonium salt. The nitrogen center substituted with two methyl groups and two stearyl groups.
Quaternium-15 (systematic name: hexamethylenetetramine chloroallyl chloride) is a quaternary ammonium salt that has been used as a surfactant and preservative. It acts as an antimicrobial agent because it slowly releases formaldehyde , which is a preservative with biocidal properties.
A bit of salt in the diet is necessary for good health. The seasoning is also a kitchen staple and taste booster, but Americans consume way too much — usually without even picking up a saltshaker.
Like many other disinfecting cleaners, the active ingredient in Lysol is a quaternary ammonium compound, also referred to as a QAC or quat. Lysol introduced one of the first QACs in the late 1880s ...
In another use of the term in organic chemistry, a quaternary compound is or has a cation consisting of a central positively charged atom with four substituents, especially organic (alkyl and aryl) groups, discounting hydrogen atoms. [1] The best-known quaternary compounds are quaternary ammonium salts, having a nitrogen atom at the center. [2]
In mice this disinfectant was found to cause infertility and birth defects when combined with Alkyl (60% C14, 25% C12, 15% C16) dimethyl benzyl ammonium chloride (ADBAC). [ 5 ] [ 6 ] These studies contradict the older toxicology data set on quaternary ammonia compounds which was reviewed by the U.S. Environmental Protection Agency (U.S. EPA ...
Dequalinium is a quaternary ammonium cation and bolaamphiphile commonly available as the dichloride salt. It is useful as an antiseptic and disinfectant. The bromide, iodide, acetate, and undecenoate salts are known as well. Dequalinium chloride is the active ingredient of several medications.
