Chemical Structure

PF-543 D8 CAS 1415562-82-1 chemical structure

Description

CATO manufactures PF-543 D8 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.

PF-543 D8 (CAS 1415562-82-1), molecular formula C27H31NO4S and molecular weight 465.60 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of PF-543 D8 (C27H31NO4S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
