T-1152 is a quaternary carbamate anticholinesterase. It is synthesized by reaction of m-dimethylaminophenol with methyl isocyanate, followed by quaternization with methyl iodide.^[3] Since T-1152 is toxic by ingestion, it was patented as a rodenticide in 1932.^[2]

The chloride and methylsulfate salt of T-1152 is T-1690 (TL-1226) and AR-13, respectively.^[1]
