Description
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
Thiocolchicoside EP Impurity H (10-Demethoxy Colchicoside) (CAS CATO-C4X-27704) is a certified pharmaceutical impurity reference standard with the molecular formula C26H31NO10 and a molecular weight of 517.53 g/mol.
Based on its molecular formula C26H31NO10, Thiocolchicoside EP Impurity H (10-Demethoxy Colchicoside) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 517.53 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
