4-Pyridinecarboxylic acid

Description:

4-Pyridinecarboxylic acid, also known as nicotinic acid or niacin, is a heterocyclic organic compound with the molecular formula C6H5NO2. It features a pyridine ring substituted with a carboxylic acid group at the 4-position. This compound is a colorless to pale yellow solid that is soluble in water, ethanol, and ether, making it versatile for various applications. It has a characteristic odor and is known for its role as a vitamin (vitamin B3) in biological systems, essential for metabolic processes. 4-Pyridinecarboxylic acid exhibits weak acidity due to the presence of the carboxylic acid functional group, and it can participate in various chemical reactions, including esterification and amidation. Additionally, it is used in the synthesis of pharmaceuticals, agrochemicals, and as a precursor for the production of other nitrogen-containing compounds. Its safety profile indicates that it is generally regarded as safe when used appropriately, although high doses may lead to side effects.

Isonicotinic acid

CAS: 55-22-1

Isonicotinic acid is an intramolecular hydrogen compound that has been shown to have antimicrobial activity. It has the ability to bind to the surface of bacteria and inhibit their growth by forming a complex with water vapor. Isonicotinic acid also inhibits the growth of subcutaneous tumors in mice and is believed to have anti-inflammatory properties. Isonicotinic acid may be a non-toxic agent for the treatment of bacterial infections because it does not react with human serum or cause hemolysis.
