1-(4-Chlorophenyl)silatrane is an extremely toxic[2] organosilicon compound which was developed by M&T Chemicals as a single-dose rodenticide.

[1] 1-(4-Chlorophenyl)silatrane was one of the chemicals studied in the Project Coast.

[3][4] 1-(4-Chlorophenyl)silatrane is a GABA receptor antagonist[5] and it destroys nervous functions in the central nervous system of vertebrates, primarily in the brain and possibly in the brain stem.

[6][7][8] It's a rapid acting convulsant, causing convulsions within 1 minute in mice and rats.

[2] In field trials, it was less effective than zinc phosphide against wild rats.
