Description: Anaxirone is a synthetic triepoxide alkylating agent with potential antineoplastic activity. Anaxirone alkylates DNA via actual or derived epoxide groups, resulting in inhibition of DNA synthesis. This agent has been shown to exhibit a broad spectrum of antineoplastic activity against experimental tumors, including those resistant to other alkylating agents.

Preparing Stock Solutions

The following data is based on the product molecular weight 269.2539 Batch specific molecular weights may vary from batch to batch due to the degree of hydration, which will affect the solvent volumes required to prepare stock solutions.

Select a batch to recalculate based on the batch molecular weight:
Concentration / Solvent Volume / Mass 1 mg 5 mg 10 mg
1 mM 1.15 mL 5.76 mL 11.51 mL
5 mM 0.23 mL 1.15 mL 2.3 mL
10 mM 0.12 mL 0.58 mL 1.15 mL
50 mM 0.02 mL 0.12 mL 0.23 mL
