Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 470.52 g/mol gives Tafluprost Impurity 3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Tafluprost Impurity 3 (CAS 2920059-96-5), a pharmacopoeial impurity reference standard (molecular formula C25H33F3O5, MW 470.52 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Tafluprost Impurity 3 (C25H33F3O5) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 3 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.
