I need to know where I can find or purchase a very small quantity of pure Dopamine. I need it for the purification step in extraction from a crude sample. If anyone has any information on where and how I can find this compound, please let me know at the earliest since the testing is to be conducted in December.

Thank you.
Dominique.

This Dopamine Hydrochloride that you told me about, is it L-Dopamine? Because that's the one that works in human beings. Its within my project budget and so I think I'll purchase it. Is the price along with the shipment charges or without?.... I feel it doesn't really matter if it is L or D Dopamine because the molecular weight will be the same and that is what i need for the next step and it will only be used as a standard and a marker.

Thank you for the great help!
Regards,
Dominique.

The proportions of the L- and D-Dopamine for the Dopamine Hydrochloride are not stated on the product page web page.

I would assume a chiral mixture when you make up the solution.
