Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 268.23 g/mol gives Inosine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Inosine (CAS 58-63-9) is a high-purity analytical reference standard with the molecular formula C10H12N4O5 and a molecular weight of 268.23 g/mol.
Structurally, Inosine (C10H12N4O5) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 268.23 g/mol, it falls into the medium-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.
As a certified reference material (CRM), Inosine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
