Cetylpyridinium chloride is the chloride salt form of cetylpyridinium, a quaternary ammonium with broad-spectrum antimicrobial activity. Upon topical administration, cetylpyridinium chloride is positively charged and reacts with the negatively charged microbial cell surfaces, thereby destroying the integrity of the cell membrane.
N2-Isobutyryl-2′-O-methyl-guanosine (IBG) is a modified nucleoside that has gained significant attention in recent years due to its potential therapeutic and industrial applications. IBG is a derivative of guanosine, a nucleoside that is a building block of RNA and DNA.
Trimethylaluminium belongs to class of organometallics. It is a highly reactive chemical and its solution in toluene is normally used to facilitate workability. Its general applications are in cross coupling and carboalumination reactions.
Octenidine dihydrochloride is a cationic surfactant, with a gemini-surfactant structure. Since 1987, it has been used primarily in Europe as an antiseptic prior to medical procedures, including on neonates. It is safe to handle and chemically stable.
Allyl Glycidyl Ether (AGE) is a multifunctional organic intermediate made from epichlorohydrin and allyl chloride and is featured by high functionality and low chlorine content. Since it has an epoxy group and an allyl group, AGE reacts with a wide range of compounds.
Liposomal iron involves encapsulating iron molecules within lipid bilayers. This encapsulation protects the iron from interactions with other compounds, enhance its stability, improve its bioavailability and low incidence of side effects.
Polyethylene glycols (PEG), also known as macrogols, are liquid or solid polymers of the general formula H(OCH2CH2)n OH, where n is greater or equal to four.
