Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Goserelin Impurity 42 TFA Salt.
Goserelin Impurity 42 TFA Salt (CAS CATO-C4X-192042) is a certified pharmaceutical impurity reference standard with the molecular formula C25H48N10O6C2HF3O2 and a molecular weight of 698.75 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Goserelin Impurity 42 TFA Salt is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 698.75 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 Goserelin Impurity 42 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.
