Chemical Structure

Nijmegen-1 CAS 159155-03-0 chemical structure

Description

Nijmegen-1 (CAS 159155-03-0), molecular formula C17H13NO7 and molecular weight 343.29 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Nijmegen-1 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 343.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), Nijmegen-1 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.
