Carbaryl CAS 63-25-2 Pharmaceutical Raw Materials Agricultural Chemical Pesticides

 

1. Introduction
It is a chemical in the carbamate family used chiefly as an insecticide. It is a colorless white crystalline solid. Its safety is somewhat controversial. It is a cholinesterase inhibitor and can be toxic to humans with excessive exposure, though no known fatalities have been reported. It is classified as a likely human carcinogen by the EPA.

 

It kills various beneficial insect and crustacean species along with the pests it is intended for, so care must be taken when spraying in areas where such species are present. Carbaryl is acutely toxic to honeybees and can destroy colonies of bees that are foraging in an area where the chemical has been applied.

 

2. Usage

 

(1) Cholinesterase inhibitor. Ectoparasiticide
(2) Labelled Prifinium Bromide, a synthetic antispasmodic drug; parasympatholytic. Prifinium Bromide is used as a quartenary anticholinergic agent.
3. General Description

 

A white crystalline solid. Insoluble in water. Combustible, although difficult to ignite. Toxic by inhalation (dust, etc.). Produces toxic oxides of nitrogen during combustion.
