Frequently asked questions

What is DL-Penicillamine used for?

DL-Penicillamine is used in research as a chelating agent for heavy metals and as the racemic starting material from which D-penicillamine can be resolved. It is not used therapeutically. Indications such as Wilson's disease and rheumatoid arthritis apply only to D-penicillamine, because the L-isomer is toxic.

What is the chemical formula and molecular weight of DL-Penicillamine?

The formula is C5H11NO2S with a molecular weight of 149.21 g/mol.

How should DL-Penicillamine be stored?

Store at 2 to 8 °C; protect from light and moisture.

What grade of DL-Penicillamine is available?

Available in pharmaceutical grade for research use.

Can Molekula supply DL-Penicillamine in bulk?

Yes, Molekula offers bulk quantities upon request; please contact sales for details.

What documentation comes with a DL-Penicillamine order?
