  <description>Aciclovir is an organic compound with the chemical formula C8H11N5O3 and an average molecular weight of 225.20 g/mol. Aciclovir belongs to the purines and purine derivatives, a subclass of imidazopyrimidines within the organic compounds. In terms of biological activity, it acts as an inhibitor of the DNA polymerase catalytic subunit.

The substance is found in or released from eight recorded sources. These include drinking water and water supply (drinking water), electrical and electronic equipment (antennas), building and construction (tents or canopies, floors), and healthcare, pharmaceuticals and veterinary products, specifically including antivirals, antiinfectives, antibiotics, and chemotherapeutics. Recorded exposure routes for the compound include oral, intravenous, inhalation, buccal, cutaneous, topical, and ophthalmic pathways.</description>
