Chemical Structure

Tafluprost Impurity 21 CAS CATO-C4X-216321 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 432.52 g/mol gives Tafluprost Impurity 21 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Tafluprost Impurity 21 (CAS CATO-C4X-216321), a pharmacopoeial impurity reference standard (molecular formula C25H33FO5, MW 432.52 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Tafluprost Impurity 21 (C25H33FO5) contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 432.52 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 21 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.
