General description

Risedronate Related Compound C is an impurity of risedronate, belonging to the group of pyridinyl bisphosphonates, and is effectively used in the treatment of Paget′s disease of bone. It is also used for the treatment of skeletal disorders since it inhibits osteoclast-mediated bone resorption and modulates bone metabolism.


Risedronate may be used as a pharmaceutical reference standard for the quantification of the analyte in pharmaceutical formulations using reversed-phase ion-pair high-performance liquid chromatographic method.

These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.

Analysis Note

These secondary standards offer multi-traceability to the USP, EP and BP primary standards, where they are available.
