How are pyridinium salts formed?

Pyridinium salts are commonly formed via N-alkylations of pyridines. Pyridines react with alkyl iodides <08JMC760; 08BMC3825; 08OBC175; 08JMC502; 08EJM675; 08OL321>, bromides <08H887; 08JMC760; 08JA4105>, chlorides <08BMC1493>, and mesylates <08H1213> to form the corresponding pyridinium salts.

Is pyridinium chloride an acid or base?

Pyridinium chloride is an acidic salt of a weak base (pyridine) and a strong acid (HCl).

What is pyridinium chloride used for?

Cetylpyridinium chloride is a pyridinium salt that has N-hexadecylpyridinium as the cation and chloride as the anion. It has antiseptic properties and is used in solutions or lozenges for the treatment of minor infections of the mouth and throat. It has a role as an antiseptic drug and a surfactant.

Is pyridinium ion stable?

1.6. 3.4 Other pyridinium ions. Pseudo-bases derived from pyridinium ions carrying a strongly electron-withdrawing substituent on the nitrogen atom are unstable and undergo ring fission with hydroxide ions under mild conditions (NaOH–H2O, 20 °C).

Is pyridinium ion an acid?

We can write potential reactions for both the pyridinium and chloride ions reacting with water as follows. Note that this is the Ka reaction for pyridinium. Looking in the table of values shows a pKa of 5.22. This means that pyridinium is a weak acid.
