Carbanolate (Ref: U12927)
Last updated: 07/01/2024
(Not known by any other names)

SUMMARY
Carbanolate is an obsolete carbamate insecticide. It has a moderate aqueous solubility. There are significant gaps in reported data for environmental fate and ecotoxicity. However, it is highly toxic to mammals and likely to bioaccumulate. It is also a neurotoxin and an acetyl cholinesterase inhibitor.
