3-Pyridinecarboxylic acid, hydrochloride (1:1)

Description:

3-Pyridinecarboxylic acid, hydrochloride (1:1), also known as nicotinic acid hydrochloride, is a chemical compound characterized by its pyridine ring structure with a carboxylic acid functional group. This compound appears as a white to off-white crystalline powder and is soluble in water, reflecting its ionic nature due to the presence of the hydrochloride salt. It has a molecular formula that includes carbon, hydrogen, nitrogen, and oxygen, contributing to its acidic properties. The substance is often used in biochemical applications, particularly in the synthesis of pharmaceuticals and as a precursor in the production of niacin (vitamin B3). Its role in biological systems includes participation in metabolic processes and enzyme functions. As a hydrochloride salt, it is more stable and easier to handle than its free acid form. Safety data indicates that it should be handled with care, as it may cause irritation to the skin, eyes, and respiratory tract. Proper storage conditions should be maintained to preserve its integrity and efficacy.
