Common Name

Acetylisoniazid

Description

Acetylisoniazid belongs to the class of organic compounds known as pyridinecarboxylic acids and derivatives. Pyridinecarboxylic acids and derivatives are compounds containing a pyridine ring bearing a carboxylic acid group or a derivative thereof. Acetylisoniazid is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review very few articles have been published on Acetylisoniazid.
