  <description>Neostigmine is an organic compound with the chemical formula C12H19N2O2 and an average molecular weight of 223.29 g/mol. Neostigmine belongs to the phenoxy compounds, a subclass of benzene and substituted derivatives within the organic compounds. It is categorized under the superclass of benzenoids. In terms of biological activity, neostigmine acts as an inhibitor of the protein target acetylcholinesterase (ACHE).

The compound is found in or released from seven recorded sources. These include pharmaceuticals and veterinary products, specifically miotics, antiglaucoma preparations, and parasympathomimetics. It is also associated with food, cookware, and food processing, specifically the preparation of vinegar and food preservation. Additionally, it is found in household cleaning and consumer products, such as tobacco smoke filters and non-electric simulated smoking devices, as well as in electrically stimulated smoking devices. Recorded exposure routes for neostigmine include oral, subcutaneous, intravenous, and intramuscular administration.</description>
