Dihydrostreptomycin Sesquisulfate Hydrate (CAS 5490-27-7) is a high-purity analytical reference standard with the molecular formula C21H41N7O12H2O4S and a molecular weight of 681.67 g/mol.
Structurally, Dihydrostreptomycin Sesquisulfate Hydrate (C21H41N7O12H2O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 681.67 g/mol, it falls into the high-molecular-weight range. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
