Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 438.50 g/mol gives Tafluprost Impurity 17 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Tafluprost Impurity 17 (CAS 209860-89-9), a pharmacopoeial impurity reference standard (molecular formula C24H32F2O5, MW 438.50 g/mol) used for the identification and quantification of trace impurities in APIs.
Tafluprost Impurity 17 (C24H32F2O5) contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, 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).
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 17 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.
