Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Rac-Melphalan EP Impurity G Ditrifluoroacetate (Rac-Melphalan Dimer Ditrifluoroacetate).
Rac-Melphalan EP Impurity G Ditrifluoroacetate (Rac-Melphalan Dimer Ditrifluoroacetate) (CAS CATO-C4X-19887) is a certified pharmaceutical impurity reference standard with the molecular formula C26H35Cl3N4O4C2HF3O2 and a molecular weight of 687.96 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, Rac-Melphalan EP Impurity G Ditrifluoroacetate (Rac-Melphalan Dimer Ditrifluoroacetate) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 687.96 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 Rac-Melphalan EP Impurity G Ditrifluoroacetate (Rac-Melphalan Dimer Ditrifluoroacetate) 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.
