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 chloride an acid?
Looking in the table of values shows a pKa of 5.22. This means that pyridinium is a weak acid. Note that this is the Kb reaction for chloride. Chloride is the conjugate base of hydrochloric acid.

Is cetylpyridinium chloride safe for skin?
Cetylpyridinium chloride, a preservative used in oral hygiene products, skin lotions and deodorants, is safe for use at specific concentrations, according to the European Commission’s Scientific Committee on Consumer Safety (SCCS).
Is pyridinium salt aromatic?
Pyridinium cations are aromatic, as determined through Hückel’s rule. They are isoelectronic with benzene.
Is pyridinium cation aromatic?
What is pyridinium salt?
In principle, pyridinium salts are highly reactive species in comparison with pyridine heterocycles. They undergo various nucleophilic addition reactions with a variety of nucleophiles for the preparation of functionalized dihydro, and tetrahydropyridines, as well as piperidines.
What is the molecular formula of a compound that has an empirical formula of C5H5N?
PYRIDINE Formula – C5H5N – Over 100 million chemical compounds | Mol-Instincts.
What is the molar mass of kno2?

What is the kb of pyridine?
The Kb of pyridine (C5H5N)is 1.70×10-9.
What happens if you drink cetylpyridinium chloride?
Ingestion of cetylpyridinium chloride in large doses may cause gastric upset and central nervous system depression 9. However, such overdose symptoms are only observed in doses 70 times greater than the concentrations of cetylpyridinium chloride found in most over-the-counter cetylpyridinium chloride products 9.
How are pyridinium salts formed?
Pyridinium salts are commonly formed via N-alkylations of pyridines.
Is pyridinium ion stable?
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).
Why is pyridinium ion aromatic?
Its salts are often insoluble in the organic solvent, so precipitation of the pyridinium leaving group complex is an indication of the progress of the reaction. Pyridinium cations are aromatic, as determined through Hückel’s rule. They are isoelectronic with benzene….Pyridinium.
