Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 434.52 g/mol gives Tafluprost Impurity 19 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Tafluprost Impurity 19 (CAS CATO-C4X-216319), a pharmacopoeial impurity reference standard (molecular formula C25H32F2O4, MW 434.52 g/mol) used for the identification and quantification of trace impurities in APIs.
Tafluprost Impurity 19 (C25H32F2O4) contains a flavonoid core, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Tafluprost Impurity 19 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.
