Chemical Structure

Tafluprost Impurity 20 CAS 3446-89-7 chemical structure

Description

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 supplies Tafluprost Impurity 20 (CAS 3446-89-7), a pharmacopoeial impurity reference standard (molecular formula C8H8OS, MW 152.21 g/mol) used for the identification and quantification of trace impurities in APIs.

Tafluprost Impurity 20 (C8H8OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

As a certified reference material (CRM), Tafluprost Impurity 20 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
