C6H4O3
C6H4O3 refers to a molecular formula that can represent several different chemical compounds. The most common and notable compound with this formula is quinic acid. Quinic acid is a naturally occurring organic acid found in many plants, particularly in coffee beans, where it contributes to the bitter taste and acidity. It is also present in fruits like apples, peaches, and prunes. Chemically, quinic acid is a cyclic polyol and carboxylic acid. Its structure features a cyclohexane ring with a carboxyl group and four hydroxyl groups attached. Quinic acid has been studied for its antioxidant properties and its potential role in various metabolic processes. Another less common isomer with the formula C6H4O3 is muconic acid, which exists in different geometric forms (cis,cis; cis,trans; trans,trans). Muconic acids are dicarboxylic acids that can be produced through the breakdown of aromatic compounds by microorganisms. The specific compound implied by C6H4O3 depends on the context of the chemical discussion.
