Medchemexpress LLC Rimantadine-d4 hydrochloride | 350818-67-6 | 99.0% | 1 MG
Rimantadine-d4 hydrochloride is a deuterium-labeled version of Rimantadine hydrochloride, an orally active antiviral compound. It functions as an inhibitor for the M2 protein, which is crucial for blocking the hydrogen ion channel activity of the virus, thereby preventing its entry and replication. This mechanism of action provides broad-spectrum antiviral activity. This compound is particularly useful in research for quantitation during drug development and as an internal standard for quantitative analysis.
- Can be used as a tracer
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS
- Deuterium-labeled compound
- Exhibits broad-spectrum antiviral activity
- Blocks hydrogen ion channel activity
