Chemical Structure
Description
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.
Risedronate Related Compound B (CAS CATO-C4X-17508) is a high-purity analytical reference standard with the molecular formula C14H16N2O12P4NaH2O and a molecular weight of 569.18 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, Risedronate Related Compound B is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 569.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
As a certified reference material (CRM), Risedronate Related Compound B 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.
