The occurrence of Pamidronate EP Impurity C is closely related to a phosphonate group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Pamidronate EP Impurity C (CAS 10294-56-1), molecular formula H3O3P and molecular weight 82.00 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula H3O3P, Pamidronate EP Impurity C contains a phosphonate group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 82.00 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.
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), Pamidronate EP Impurity C 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.
