Malathion β-monoacid (Cat No.: R052309) is a primary degradation product of malathion, an organophosphate insecticide widely used in agriculture and public health. This compound forms when malathion undergoes hydrolysis, losing one of its ester groups. Malathion β-monoacid retains some insecticidal activity, but it is less potent than its parent compound. Research on malathion β-monoacid focuses on its environmental fate, toxicity, and potential impact on non-target organisms, aiding in the assessment of the ecological risks associated with malathion use.
