Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 195.19 g/mol gives Letermovir Impurity 97 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Letermovir Impurity 97 (CAS CATO-C4X-291597) is a certified pharmaceutical impurity reference standard with the molecular formula C10H10FNO2 and a molecular weight of 195.19 g/mol.
Letermovir Impurity 97 (C10H10FNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 Letermovir Impurity 97 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.
