= Tetradecyltrimethylammonium bromide
<Tetradecyltrimethylammonium bromide> is a cationic <surfactant> with a fourteen-carbon hydrophobic chain and a positively charged trimethylammonium headgroup; bromide supplies the counterion.
In <water>, aggregation into <micelles> depends on concentration and solution conditions. Comparing related surfactants with different chain lengths helps separate the influence of hydrophobic chain size from that of the charged headgroup.https://www.ebi.ac.uk/chebi/CHEBI:3565[ChEBI: cetrimide, chemical identity and structure]{ref}
