Chemical Structure

Uk-157147 CAS 162704-20-3 chemical structure

Description

Uk-157147 (CAS 162704-20-3), molecular formula C23H24N2O7S and molecular weight 472.51 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Uk-157147 (C23H24N2O7S) is characterized by a flavonoid 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.

As a certified reference material (CRM), Uk-157147 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.
