Cetylpyridinium Chloride (Hexadecylpyridinium Chloride) is a cationic quaternary ammonium compound used as oropharyngeal antiseptic.

Jatrorrhizine (neprotin) is a protoberberine alkaloid isolated from Enantia chlorantha (Annonaceae) and other species. It was found to have antimicrobial and antifungal activity. It binds and noncompetitively inhibits monoamine oxidase (IC50 4 micromolar for MAO-A and 62 for MAO-B).

Jatrorrhizine chloride (Neprotine chloride) is a potent and orally active uptake-2 transporter inhibitor. It exhibits a critical neuroprotective role in H2O2-induced apoptosis via inhibition of the MAPK pathway in HT22 hippocampal neurons.

Coryneine (Trimethyl(3,4-dihydroxyphenethyl)aminium) is a quaternary ammonium derivative of dopamine derived from aconite root.

Benzalkonium chloride (Alkyldimethylbenzylammonium chloride) is a cationic surface-acting agent containing the quaternary ammonium group. It has three main categories of use: as a cationic surfactant, a biocide, and phase transfer agent in the chemical industry. This compound is a heterogeneous mixture of alkylbenzyldimethylammonium chlorides of multiple even-numbered alkyl chain lengths.

Benzethonium chloride (Quatrachlor) is a synthetic quaternary ammonium salt with surfactant, antiseptic, and broad spectrum antimicrobial properties.

Berberine sulfate (Berberal) is a quaternary ammonium salt of the benzylisoquinoline alkaloid proto-berberines, which can be used in the study of type 2 diabetes mellitus, abdominal obesity and metabolism-related fatty liver disease.

Cetrimonium bromide (Lauroseptol) is is a mixture of different quaternary ammonium salts, which is a known component of the broad-spectrum antiseptic cetrimide.

Diphenmanil methylsulfate (Diphemanil mesylate), a quaternary ammonium anticholinergic, binds muscarinic acetylcholine receptors and thus decreases secretory excretion of stomach acids, sweat, and saliva.

Cetylpyridinium chloride monohydrate (Hexadecylpyridinium chloride monohydrate) , a cationic quaternary ammonium compound, is used in certain classes of throat sprays, mouthwashes, lozenges, toothpaste, nasal sprays, and breath sprays. Cetylpyridinium chloride monohydrate has also been used as an ingredient in certain pesticides. It is an antiseptic with killing bacteria and other microorganisms. It can be potent in reducing gingivitis and preventing dental plaque. It may result in brown stains between the teeth and on the surface of teeth.

Propantheline bromide (Pro-Banthine) competitively antagonizes acetylcholine activity mediated by muscarinic receptors at neuroeffector sites on smooth muscle and exocrine gland cells. Propantheline Bromide is the bromide salt form of propantheline, a quaternary ammonium compound structurally related to belladonna alkaloids. An aspartic acid residue present in the N-terminal portion of the third transmembrane helix of the muscarinic receptor is believed to form an ionic bond with the tertiary or quaternary nitrogen of the antagonist. Antagonism leads to a reduction of exocrine glands secretions and to relax the bronchial muscle and reduce tone and motility of intestinal smooth muscle.

Denatonium benzoate (THS-839) , a quaternary ammonium cation, is a compound of a salt with an inert anion like saccharide or benzoate. Its structure is involved in the local anesthetic lidocaine which difference only is the addition of a benzyl group to the amino nitrogen.

Acetylcholine Chloride is the chloride salt form of acetylcholine, a synthetic, quaternary amino alcohol with cholinergic properties. Acetylcholine chloride (Pilofrin) mimics the parasympathomimetic effect of the endogenous compound acetylcholine. Administered as an ophthalmic solution, this drug stimulates the cholinoceptors in the sphincter muscle of the iris, causing the pupil to constrict.

Vecuronium bromide (ORG NC 45) is a synthetic, intermediate-acting, mono-quaternary steroid that functions as a non-depolarizing neuromuscular blocking agent with muscle relaxant properties.

Methacholine Chloride (Acetyl-β-methylcholine chloride) is a quaternary ammonium parasympathomimetic agent with the muscarinic actions of ACETYLCHOLINE. It is hydrolyzed by ACETYLCHOLINESTERASE at a considerably slower rate than ACETYLCHOLINE and is more resistant to hydrolysis by nonspecific CHOLINESTERASES so that its actions are more prolonged. It is used as a parasympathomimetic bronchoconstrictor agent and as a diagnostic aid for bronchial asthma.

L-Carnitine hydrochloride ((R)-Carnitine hydrochloride) is a highly polar small zwitterionic molecule that functions as an essential cofactor for mitochondrial β-oxidation. L-Carnitine hydrochloride facilitates the transport of long-chain fatty acyl-CoAs into mitochondria for subsequent degradation via β-oxidation, thereby supporting cellular energy metabolism. L-Carnitine hydrochloride also displays antioxidant activity and can mitigate metabolic imbalances associated with numerous inborn errors of metabolism, positioning it as an important agent in metabolic research.

Phenoxyethanol (NSC-1864) is germicidal. It often used together with quaternary ammonium compounds.

Lauryl benzalkonium chloride (Benzododecinium chloride) is a quaternary ammonium compound.Benzododecinium chloride is an irritant for eye.

DDAC (Quaternium 12), also known as Didecyldimethylammonium chloride, is a dialkyl-quaternary ammonium compound widely utilized in various products due to its bactericidal, virucidal, and fungicidal characteristics.

(±)-Carnitine chloride (Monocamin) is a quaternary ammonium compound biosynthesized from the amino acids lysine and methionine.

N-Octyl-β-D-thioglucopyranoside (octylthioglucoside, OTG) is a mild nonionic detergent characterized by a thioglycosidic linkage that is used for effective cell lysis or to solubilise integral membrane proteins without denaturing their tertiary or quaternary structure; this property is particularly of use in order to crystallise them for structural studies or to reconstitute them into artificial lipid bilayers for functional assays.

Tetraethylammonium chloride is a quaternary ammonium compound. It is a non-selective potassium channel blocker. It is a good substrate for organic cation transporter proteins and has antitumor properties.

Prifinium bromide is a quaternary ammon antimuscarinic. It inhibits hyperkinesia of the digestive organs and urinary tract and has a spasmolytic action.

iron chloride hexahydrate promoted selective hydroxylation and chlorination of benzyl ketone derivatives for the construction of hetero-quaternary scaffolds.
