General description

6-Propyl-2-thiouracil or 6-n-Propylthiouracil (PROP) is a compound with a bitter taste.

Application

6-Propyl-2-thiouracil is a thyreostatic (thyroid hormone) agent that may be used as a reference material in thyreostatic drug separation and detection technologies such as capillary electrophoresis, high performance liquid chromatography (HPLC), or gas chromatography.
6-Propyl-2-thiouracil (PROP) has been used to impregnate on disk for PROP taster status studies for sensory characterization in a defined human sample group. It has been used as a screening agent for testing the intensity of taste by labeled magnitude scale (LMS).

Packaging

10, 25, 100 g in glass bottle

Biochem/physiol Actions

6-Propyl-2-thiouracil (6-PTU), a potential inhibitor of D1 iodothyronine deiodinase, is involved in the deiodination of iodothyronines. It is an uncompetitive inhibitor of iodothyronine substrates.
