Description
As a certified reference material (CRM), Telmisartan Impurity 78 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.
Telmisartan Impurity 78 (CAS CATO-C4X-135978) is a certified pharmaceutical impurity reference standard with the molecular formula C7H9ClN2HCl and a molecular weight of 193.07 g/mol.
Based on its molecular formula C7H9ClN2HCl, Telmisartan Impurity 78 contains a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 193.07 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
