N-Alkylpyridinium chloride

D.1.2. N-alkylpyridinium-Containing Ionic Liquids. The melting point of N-alkylpyridinium chloride increases from 70 to 80°C when the alkyl chain is lengthened from Ci2 to Cig. The melting point of iV-alkylpyridinium [NiCl4]J changes only from 80 to 86°C as the substituent changes from C12 to Cig 62). 

When an electric field was applied to a sheet of PAMPS gel suspended in an N-alkylpyridinium chloride (C PyCl) surfactant solution, the gel showed significant and rapid bending toward the anode (Fig. 13). Among the surfactants used, C, PyCI and CijPyCl induced intense, steady bending with a magnitude of 4-6 mm within... 

Several over-the-counter mouthwashes contain an N-alkylpyridinium chloride as an antibacterial agent.
