Dantrolene Sodium has several amine groups that can interact with lone-silanols causing problematic peak tailing when analyzed with conventional HPLC columns. By utilizing a Bidentate C18™ Column with its Silica Hydride™ surface, challenging compounds like Dantrolene can be readily retained with symmetrical peak shape.

Note: Essential to muscle contraction are Ryanodine Receptors that regulate the release of Calcium from the Sarcoplasmic Reticulum of muscle cells. Dantrolene Sodium is a postsynaptic muscle relaxant that lessens the “excitation-contraction” coupling response in these cells. It achieves this by inhibiting Calcium binding to Ryanodine Receptor 1 and decreasing intracellular Calcium concentrations.
