(N-HEXYL)TRIMETHYLAMMONIUM BROMIDE

Synonym(s):N,N,N-Trimethylhexylammonium bromide

white solid

Hexyltrimethylammonium bromide (HTAB) can be used as:

A phase transfer catalyst to synthesize polyether via polycondensation of α, α′-dichloro-p-xylene with 2,2-bis(4-hydroxyphenyl)propane.
A reagent in the preparation of ZSM-5 zeolites to tune ZSM-5 particles with a scroll-like shape and hierarchical pores.
A surface-active agent to create the hydrophobic environment around metal nanoparticles (MNPs) even in water. This technique is highly suitable for using MNPs as electron-counting components in biosensors.

Hexyltrimethylammonium bromide is a useful phase transfer catalyst

Recrystallise it from acetone. It is extremely hygroscopic. [McDowell and Kraus J Am Chem Soc 73 2170 1951, Beilstein 4 IV 710.]
