3-Pyridinecarboxylic acid, 6-formyl-, ethyl ester

Description:
3-Pyridinecarboxylic acid, 6-formyl-, ethyl ester, also known as ethyl 6-formyl-3-pyridinecarboxylate, is an organic compound characterized by its pyridine ring structure, which includes a carboxylic acid and an aldehyde functional group. This compound typically appears as a colorless to pale yellow liquid or solid, depending on its purity and form. It is soluble in organic solvents such as ethanol and acetone but has limited solubility in water due to its hydrophobic pyridine ring. The presence of both the carboxylic acid and aldehyde groups makes it a versatile intermediate in organic synthesis, particularly in the preparation of various pharmaceuticals and agrochemicals. Its reactivity is influenced by the electron-withdrawing nature of the pyridine nitrogen, which can participate in various chemical reactions, including condensation and esterification. Safety data indicates that it should be handled with care, as it may cause irritation to the skin and eyes. Proper storage in a cool, dry place away from light is recommended to maintain its stability.
