Dopamine Chemical Properties, Uses, Production

Chemical Properties

Flake crystals. Melting point: 218-220℃.

Uses

3-Hydroxytyramine hydrobromide was used in the preparation of dopamine standards to measure the dopamine release and uptake in striatal brain slices from R6/1 HD model mice by fast-scan cyclic voltammetry. It was employed as internal standard in the determination of catecholamines in biological tissues by liquid chromatography.
