Description
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.
Tizanidine impurity 17 (CAS CATO-C4X-144517) is a certified pharmaceutical impurity reference standard with the molecular formula C9H9ClN4O2 and a molecular weight of 240.65 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Tizanidine impurity 17 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 240.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures Tizanidine impurity 17 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.
