In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Synthesis and microbiological properties of novel bis-quaternary ammonium compounds based on 4,4′-oxydiphenol spacer, published in 2019-09-30, which mentions a compound: 693-67-4, Name is 1-Bromoundecane, Molecular C11H23Br, COA of Formula: C11H23Br.
Novel gemini (tail-head-spacer-head-tail) bis-quaternary ammonium compounds I [n = 7, 8, 9, etc.] with a 4,4′-oxydiphenol spacer between two pyridinium heads were synthesized and compared with commonly used antiseptics such as benzalkonium chloride and chlorhexidine gluconate. Analogs bearing C8H17, C9H19 and C10H21 aliphatic groups displayed potent broad spectrum in-vitro activity against five bacterial strains and two fungi, with min. inhibitory concentrations relatively independent of the counter ion.
From this literature《Synthesis and microbiological properties of novel bis-quaternary ammonium compounds based on 4,4′-oxydiphenol spacer》,we know some information about this compound(693-67-4)COA of Formula: C11H23Br, but this is not all information, there are many literatures related to this compound(693-67-4).
