Chemical Structure

PF-543 Citrate CAS 1415562-83-2 chemical structure

Description

PF-543 Citrate (CAS 1415562-83-2) is a high-purity analytical reference standard with the molecular formula C27H31NO4SC6H8O7 and a molecular weight of 657.73 g/mol.

PF-543 Citrate (C27H31NO4SC6H8O7) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; 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).

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.

CATO manufactures PF-543 Citrate 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.
