The Uses of 2-Propylpiperidine

Coniine is present in all parts of the plantpoison hemlock (Conium maculatum). It isthe first alkaloid to be synthesized and structure determined. Because of its high toxicity,its clinical application is very limited.

What are the applications of Application

(±)-Coniine is a toxin found in poison hemlock

Health Hazard

Coniine is a highly toxic alkaloid. Thetoxic symptoms from ingestion are weakness,drowsiness, nausea, vomiting, muscle contraction, and labored breathing. A high dosecan cause convulsions, cyanosis, asphyxia,and death. Chronic ingestion of coniine produced adverse reproductive effects and spe cific developmental abnormalities in cattles.LD50 value, oral (mice): 100 mg/kg.
