  2. Benzalkonium chloride - Wikipedia

    en.wikipedia.org/wiki/Benzalkonium_chloride

    Benzalkonium chloride (BZK, BKC, BAK, BAC), also known as alkyldimethylbenzylammonium chloride (ADBAC) and by the trade name Zephiran, [1] is a type of cationic surfactant. It is an organic salt classified as a quaternary ammonium compound. ADBACs have three main categories of use: as a biocide, a cationic surfactant, and a phase transfer agent ...

  3. Ammonium chloride - Wikipedia

    en.wikipedia.org/wiki/Ammonium_chloride

    Infobox references. Ammonium chloride is an inorganic chemical compound with the chemical formula N H 4 Cl, also written as [NH4]Cl. It is an ammonium salt of hydrogen chloride. It consists of ammonium cations [NH4]+ and chloride anions Cl−. It is a white crystalline salt that is highly soluble in water.

  4. Benzyl chloride - Wikipedia

    en.wikipedia.org/wiki/Benzyl_chloride

    Benzyl chloride is an alkylating agent. Indicative of its high reactivity (relative to alkyl chlorides), benzyl chloride slowly reacts with water in a hydrolysis reaction to form benzyl alcohol and hydrochloric acid. In contact with mucous membranes, hydrolysis produces hydrochloric acid. Thus, benzyl chloride is a lachrymator and has been used ...

  5. Didecyldimethylammonium chloride - Wikipedia

    en.wikipedia.org/wiki/Didecyldimethylammonium...

    Didecyldimethylammonium chloride (DDAC) is a quaternary ammonium compound used as antiseptic / disinfectant. It causes the disruption of intermolecular interactions and the dissociation of lipid bilayers. The bacteriostatic (prevent growth) or bactericide (kill microorganism) activity of DDAC depends on its concentration and the growth phase of ...

    en.wikipedia.org/wiki/Ammonium_diethyl_dithio...

    Ammonium diethyl dithiophosphate or more systematically ammonium O,O′-diethyl dithiophosphate, is the ammonium salt of diethyl dithiophosphoric acid. It is used as a source of the (C 2 H 5 O) 2 PS 2− ligand in coordination chemistry and in analytical chemistry for determination of various ions. It can be obtained by the reaction of ...

  7. Benzyl group - Wikipedia

    en.wikipedia.org/wiki/Benzyl_group

    The term benzylic is used to describe the position of the first carbon bonded to a benzene or other aromatic ring. For example, (C6H5) (CH3)2C+ is referred to as a "benzylic" carbocation. The benzyl free radical has the formula C6H5CH2•. The benzyl cation or phenylcarbenium ion is the carbocation with formula C6H5CH+ 2; the benzyl anion or ...

  8. Salting out - Wikipedia

    en.wikipedia.org/wiki/Salting_out

    Salting out. Salting out (also known as salt-induced precipitation, salt fractionation, anti-solvent crystallization, precipitation crystallization, or drowning out) [1] is a purification technique that utilizes the reduced solubility of certain molecules in a solution of very high ionic strength. Salting out is typically used to precipitate ...

  9. Quaternary ammonium cation - Wikipedia

    en.wikipedia.org/wiki/Quaternary_ammonium_cation

    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 [NR4]+, where R is an alkyl group, an aryl group [ 1 ] or organyl group.
