Muconic Acid, Butadiene Dicarboxylic Acid, Hexadienedioic Acid, 505-70-4

Muconic acid is a dicarboxylic acid with three isomeric forms: trans,trans-muconic acid, cis,trans-muconic acid, and cis,cis-muconic acid. It is an important bio-based platform chemical used in the production of adipic acid, terephthalic acid, and trimellitic acid, which are key components in nylon, polyurethane, and polyethylene terephthalate (PET) plastics.

Key Properties

• Chemical Formula: C₆H₆O₄
