5-Methyl-3-pyridinesulfonic acid

Description:
5-Methyl-3-pyridinesulfonic acid is an organic compound characterized by its pyridine ring, which is a six-membered aromatic ring containing one nitrogen atom. This compound features a methyl group and a sulfonic acid group (-SO3H) attached to the pyridine ring, specifically at the 5 and 3 positions, respectively. The presence of the sulfonic acid group imparts strong acidic properties, making it a useful reagent in various chemical reactions and applications. It is typically a white to light yellow solid that is soluble in water due to the polar nature of the sulfonic acid group. This compound can be utilized in organic synthesis, particularly in the preparation of sulfonamides and other derivatives. Additionally, it may serve as a pH indicator or in the development of pharmaceuticals and agrochemicals. Safety precautions should be taken when handling this compound, as with many sulfonic acids, due to its corrosive nature and potential health hazards.
