Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 556.71 g/mol gives Meglumine Amidotrizoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Meglumine Amidotrizoate (CAS 7170-91-4), molecular formula C13H7Cl2HgN3O5 and molecular weight 556.71 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Meglumine Amidotrizoate (C13H7Cl2HgN3O5) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 556.71 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), Meglumine Amidotrizoate 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.
