Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 218.00 g/mol gives Clofarabine Impurity 11 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Clofarabine Impurity 11 (CAS CATO-C4X-159311) is a certified pharmaceutical impurity reference standard with the molecular formula C5HCl2N5O and a molecular weight of 218.00 g/mol.
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Clofarabine Impurity 11 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 218.00 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.
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 Clofarabine Impurity 11 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.
