3-Pyridinesulfonic acid, 2-chloro-

Description:
3-Pyridinesulfonic acid, 2-chloro- is an organic compound characterized by the presence of a pyridine ring substituted with a sulfonic acid group and a chlorine atom. Its molecular structure features a six-membered aromatic ring containing nitrogen, which contributes to its basicity and reactivity. The sulfonic acid group (-SO3H) imparts strong acidic properties, making it a useful reagent in various chemical reactions, particularly in sulfonation processes. The chlorine atom, located at the second position of the pyridine ring, can influence the compound's reactivity and solubility. This compound is typically a white to light yellow solid and is soluble in water due to the presence of the sulfonic acid group. It is often used in organic synthesis, pharmaceuticals, and as an intermediate in the production of dyes and agrochemicals. Safety precautions should be observed when handling this compound, as it may pose health risks if ingested or inhaled.
