Chemical Structure
Description
As a certified reference material (CRM), PF-05089771, 98% (HPLC) 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.
CATO supplies PF-05089771, 98% (HPLC) (CAS 1235403-62-9), a certified reference material (molecular formula C18H12Cl2FN5O3S2, MW 500.35 g/mol) for analytical method development and quality control.
The molecular framework of PF-05089771, 98% (HPLC) (C18H12Cl2FN5O3S2) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
