Description
CATO manufactures Pentoxifylline EP Impurity D 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.
Pentoxifylline EP Impurity D (CAS 59413-14-8) is a certified pharmaceutical impurity reference standard with the molecular formula C10H14N4O3 and a molecular weight of 238.24 g/mol.
Based on its molecular formula C10H14N4O3, Pentoxifylline EP Impurity D contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 238.24 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 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.
