Chemical Structure

Thulium(III) oxalate hydrate CAS 58176-73-1 chemical structure

Description

Structurally, Thulium(III) oxalate hydrate (C6O12Tm2H2O) contains a carbohydrate-derived structure. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 619.93 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).

Thulium(III) oxalate hydrate (CAS 58176-73-1) is a high-purity analytical reference standard with the molecular formula C6O12Tm2H2O and a molecular weight of 619.93 g/mol.

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), Thulium(III) oxalate hydrate 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.
