L-carnitine (541-15-1)  
Carnitine  ·  Vitamin BT  ·  Levocarnitine
Carnitine (β-hydroxy-γ-N-trimethylaminobutyric acid, 3-hydroxy-4-N,N,N- trimethylaminobutyrate) is a quaternary ammonium compound involved in metabolism in most mammals, plants and some bacteria. Carnitine may exist in two isomers, labeled D-carnitine and L-carnitine, as they are optically active. At room temperature, pure carnitine is a white powder, and a water-soluble zwitterion with low toxicity.
DIQUAT DIBROMIDE (85-00-7, 34417-68-0, 2764-72-9)  
Diquat
Diquat is a contact herbicide that produces desiccation and defoliation most often available as the dibromide, diquat dibromide. Brand names for this formulation include Aquacide, Dextrone, Preeglone, Deiquat, Spectracide, Detrone, Reglone, Reglon, Reglox, Tribune, Ortho-Diquat, Weedtrine-D, Weedol 2 and, in combination with glyphosate, Resolva. Diquat is a non-selective herbicide that acts quickly to damage only those parts of the plant to which it is applied.
DL-Carnitine (406-76-8, 461-06-3)  
Carnitine  ·  Vitamin BT  ·  Levocarnitine
Carnitine (β-hydroxy-γ-N-trimethylaminobutyric acid, 3-hydroxy-4-N,N,N- trimethylaminobutyrate) is a quaternary ammonium compound involved in metabolism in most mammals, plants and some bacteria. Carnitine may exist in two isomers, labeled D-carnitine and L-carnitine, as they are optically active. At room temperature, pure carnitine is a white powder, and a water-soluble zwitterion with low toxicity.
Didecyl dimethyl ammonium chloride (7173-51-5)  
didecyldimethylammonium  ·  didecyldimethylammonium chloride  ·  didecyldimethylammonium bromide
Didecyldimethylammonium chloride (DDAC) is an antiseptic/disinfectant that is used in many biocidal applications. They cause disruption of intermolecular interactions and dissociation of lipid bilayers. They are broad spectrum bactericidal and fungicidal and can be used as disinfectant cleaner for linen, recommended for use in hospitals, hotels and industries.
CHOLINE CHLORIDE (67-48-1)  
Choline  ·  Choline Bitartrate  ·  Choline Citrate
Choline chloride is an organic compound and a quaternary ammonium salt. It has a choline cation with chloride anion. Alternative names are hepacholine, biocolina and lipotril.
Chlormequat (7003-89-6, 999-81-5)  
Chlormequat is an organic compound that is used as a plant growth regulator. It is typically sold as the chloride salt, chlormequat chloride, a colorless hygroscopic crystalline substance that is soluble in water and ethanol. It is an alkylating agent and a quaternary ammonium salt.
Acetyl-DL-carnitine (14992-62-2, 870-77-9, 3040-38-8)  
Alcar  ·  Acetylcarnitine  ·  Acetyl Carnitine
Acetyl-L-carnitine, ALCAR or ALC, is an acetylated form of L-carnitine. It is naturally produced by the body, although it is often taken as a dietary supplement. Acetylcarnitine is broken down in the blood by plasma esterases to carnitine which is used by the body to transport fatty acids into the mitochondria for breakdown.
acetyl-d-carnitine (4398-79-2)  
Acetyl-L-carnitine, ALCAR or ALC, is an acetylated form of L-carnitine. It is naturally produced by the body, although it is often taken as a dietary supplement. Acetylcarnitine is broken down in the blood by plasma esterases to carnitine which is used by the body to transport fatty acids into the mitochondria for breakdown.
Quaternium-15 (4080-31-3, 194805-30-6)  
Dowicil 200  ·  1-(3-chloroallyl)-hexaminium chloride
Coptisine (3486-66-6)  
Coptisine is an alkaloid found in Chinese goldthread (Coptis chinensis). Famous for the bitter taste that it produces, it is used in Chinese herbal medicine along with the related compound berberine for treating digestive disorders caused by bacterial infections. Also found in Greater Celandine and has also been detected in Opium.
carbachol (51-83-2, 74-97-5)  
Carbamylcholine  ·  Doryl  ·  Miostat
Carbachol (Carbastat, Carboptic, Isopto Carbachol, Miostat), also known as carbamylcholine, is a cholinomimetic drug that binds and activates the acetylcholine receptor. Thus it is classified as a cholinergic agonist. It is primarily used for various ophthalmic purposes, such as for treating glaucoma, or for use during ophthalmic surgery.
choline (62-49-7)  
Choline Chloride  ·  Choline Bitartrate  ·  Choline Citrate
Choline is a water-soluble vitamin-like essential nutrient. It is a basic constituent of lecithin, which is present in many plants and animal organs. The term cholines refers to the class of quaternary ammonium salts containing the N,N,N-trimethylethanolammonium cation (X− on the right denotes an undefined counteranion).
Succinylcholine chloride (71-27-2)  
Succinylcholine  ·  Suxamethonium  ·  Anectine
Suxamethonium chloride, also known as suxamethonium or succinylcholine, is a medication used to cause short-term paralysis as part of general anesthesia. This is done to help with tracheal intubation or electroconvulsive therapy. It is given either by injection into a vein or muscle.
TETRAMETHYLAMMONIUM HYDROXIDE (75-59-2)  
tetramethylammonium  ·  tetramethylammonium chloride  ·  tetramethylammonium iodide
Tetramethylammonium hydroxide (TMAH or TMAOH) is a quaternary ammonium salt with the molecular formula N(CH3)4+ OH−. It is commonly encountered as concentrated solutions in water or methanol. The solid and solutions are colorless, or yellowish if impure.
