Description
CATO manufactures Pramipexole Impurity 83 DiHCl under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
Pramipexole Impurity 83 DiHCl (CAS 104632-25-9) is a certified pharmaceutical impurity reference standard with the molecular formula C10H17N3SHCl and a molecular weight of 247.78 g/mol.
Based on its molecular formula C10H17N3SHCl, Pramipexole Impurity 83 DiHCl contains a nitrile group, sulfur-containing functionality, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 247.78 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.
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
