Description
Minocycline EP Impurity C TFA salt (CAS 4708-96-7(Free Base)) is a certified pharmaceutical impurity reference standard with the molecular formula C22H25N3O7C2HF3O2 and a molecular weight of 557.48 g/mol.
Based on its molecular formula C22H25N3O7C2HF3O2, Minocycline EP Impurity C TFA salt contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 557.48 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.
CATO manufactures Minocycline EP Impurity C TFA salt 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.
