  <description>VANILLIC ACID (C8H8O4) is a compound with an average molecular weight of 168.15 g/mol. VANILLIC ACID belongs to the benzoic acids and derivatives, a subclass of benzene and substituted derivatives within the organic compounds. Industrially, it is utilized as a curing agent (PMC13306418), a fragrance, a flavouring, and a nutrient (PMC10850857, PMC4752411, PMC7564337, PMC9578065). Biologically, it acts as a stabilizer (PMC10850857) and an antioxidant (PMC10850857, PMC4752411, PMC7564337, PMC9578065). Its recorded protein target is chorismate pyruvate-lyase (ubiC).

The compound is found in or released from 25 recorded sources. These include food, food processing and cookware—specifically fermentation processes for beer, food preservation, preparation of malt, preparation of vinegar, and four additional sources—as well as ceilings in building and construction. It is also associated with household cleaning and consumer products, such as soap detergents, bleaching agents, perfumes within detergents and soaps, cigar cigarettes, non electric simulated smoking devices, and one other source. Furthermore, it is found in electrical and electronic equipment, including electric switches, electrodes, coils, conductors or conductive bodies characterised by the conductive materials, electrically stimulated smoking devices, and four others. Recorded exposure routes include oral, inhalation, and touch. Regarding health effects, vanillic acid has a therapeutic effect on inflammation (PMC13316579) and is used as a treatment for neurodegenerative disease (PMC4752411).</description>
