Description
As a certified reference material (CRM), Calpain Inhibitor II 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.
Calpain Inhibitor II (CAS 110115-07-6) is a high-purity analytical reference standard with the molecular formula C19H35N3O4S and a molecular weight of 401.57 g/mol.
Based on its molecular formula C19H35N3O4S, Calpain Inhibitor II contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 401.57 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
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.
