Cat.No. 3415 - DMPO | C6H11NO | CAS No. 3317-61-1
Description: Nitric oxide spin trap; measure oxygen-centered free radicals
Chemical Name: 3,4-Dihydro-2,2-dimethyl-2H-pyrrole 1-oxide

Biological Activity

Water soluble nitric oxide spin trap; allows the measurement of oxygen-centered free radicals in biological systems at room temperature using electron spin resonance (ESR). Has a high reaction rate constant for superoxide and hydroxyl radicals, and distinguishes simultaneously among a variety of important biologically generated free radicals.

Preparing Stock Solutions

The following data is based on the product molecular weight 113.16. 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 8.84 mL 44.19 mL 88.37 mL
5 mM 1.77 mL 8.84 mL 17.67 mL
10 mM 0.88 mL 4.42 mL 8.84 mL
50 mM 0.18 mL 0.88 mL 1.77 mL
