  <description>Apraclonidine is an organic compound with the chemical formula C9H10Cl2N4 and an average molecular weight of 245.11 g/mol. Apraclonidine belongs to the halobenzenes, a subclass of benzene and substituted derivatives within the organic compounds. It is categorized under the superclass of benzenoids.

The compound acts as an agonist for three recorded protein targets: the Alpha-2A adrenergic receptor (ADRA2A), the Alpha-1A adrenergic receptor (ADRA1A), and the Alpha-2B adrenergic receptor (ADRA2B). Regarding its recorded exposure routes, it is administered ophthalmically.

Apraclonidine is found in or released from seven recorded sources. Within the category of healthcare, pharmaceuticals, and veterinary products, it is used in miotics and antiglaucoma preparations. It is also associated with electrical and electronic equipment, specifically electrically stimulated smoking devices. Additionally, it is present in household cleaning and consumer products, including perfumes within detergents and soaps, tobacco smoke filters, cigar cigarettes, non-electric simulated smoking devices, and other smoking requisites.</description>
