Purity and quantity is $250 per sample (1 unit) and raw powder purity is $200 for 50 mg, with results in 3 to 5 business days. Send the material sealed and labeled, with the label claim and the form it contains.
No. The $250 test covers identity, purity and quantity by HPLC-UV for purity and assay, with LC-MS to confirm identity. Full testing to the USP Dantrolene Sodium monograph is available and quoted.
Dantrolene sodium is a hydrated salt, so the same mass contains less dantrolene than the free acid. Tell us the basis you need and the result is calculated from water content and the molecular weights.
Yes. Dantrolene is an orange nitrofuran compound that degrades on light exposure. Ship samples in opaque containers.
Usually as capsules or lyophilized powder for injection. It is poorly soluble in water, so the extraction uses an organic or basic solvent.
