Compared with other compounds in its class, the molecular weight of 504.44 g/mol gives Isopanose distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Isopanose (CAS 32581-33-2) is a high-purity analytical reference standard with the molecular formula C18H32O16 and a molecular weight of 504.44 g/mol.
Structurally, Isopanose (C18H32O16) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 504.44 g/mol, it falls into the moderately-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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Isopanose 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.
