  <common_name>Retinoic acid, 13-cis-</common_name>
  <class>SmallMolecule</class>
  <description>Retinoic acid, 13-cis- belongs to the retinoids, a subclass of prenol lipids within the organic compounds. This compound, which falls under the superclass of lipids and lipid-like molecules, has the chemical formula C20H28O2 and an average molecular weight of 300.44 g/mol. It is used for industrial pharmaceutical purposes.

The compound is found in seven recorded sources, including anti-acne preparations within healthcare, pharmaceuticals, and veterinary products. It is also present in floors used in building and construction, line transmission systems in electrical and electronic equipment, and the preparation of vinegar in food, food processing, and cookware. Additionally, it is found in household cleaning and consumer products, specifically other smoking requisites, pipe accessories, and non-electric simulated smoking devices. Recorded exposure routes for this substance include topical and oral administration. Regarding its biological activity, retinoic acid, 13-cis- has two recorded protein targets. It acts as an agonist for both the retinoic acid receptor alpha (RARA) and the retinoic acid receptor gamma (RARG), although its interaction with RARG is also categorized as other/unknown.</description>
