Beschreibung

Allgemeine Beschreibung

Thiosemicarbazide is an environmentally toxic compound, which is usually derived from thiourea. Its ability to chelate trace metals promotes its biological activity against certain tumors, protozoa, influenza, pesticides, and fungicides. It is widely used as a metal complexing agent in various fields involving the characterization of aliphatic or aromatic aldehydes, ketones, and polysaccharides.

Anwendung

Thiosemicarbazide has been used as an analytical reagent for the measurement of urea net high-affinity uptake in roots of intact maize plants using colorimetric assay.
