usage and synthesis

general description

colorless to white liquids (or tan dusts). primarily a threat to the environment. immediate steps should be taken to limit spread to the environment. easily penetrate the soil, contaminate groundwater or nearby waterways. toxic by inhalation, skin absorption and/or ingestion. used as pesticide.

air & water reactions

oxidize relatively rapidly in air. water emulsifiable.

reactivity profile

pyrethrins decompose rapidly in base; may generate heat with caustic solutions. may also react with acids to liberate heat. generate flammable hydrogen with alkali metals and hydrides.

fire hazard

some may burn but none ignite readily. containers may explode when heated. some may be transported hot.
