3-[[3,4-Dioxo-2-[[(1S)-1-phenylethyl]amino]-1-cyclobuten-1-yl]amino]-2-hydroxy-N,N-dimethylbenzamide CAS 473725-26-7

Description

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.

3-[[3,4-Dioxo-2-[[(1S)-1-phenylethyl]amino]-1-cyclobuten-1-yl]amino]-2-hydroxy-N,N-dimethylbenzamide (CAS 473725-26-7) is a high-purity analytical reference standard with the molecular formula C21H21N3O4 and a molecular weight of 379.41 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 3-[[3,4-Dioxo-2-[[(1S)-1-phenylethyl]amino]-1-cyclobuten-1-yl]amino]-2-hydroxy-N,N-dimethylbenzamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 379.41 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).

As a certified reference material (CRM), 3-[[3,4-Dioxo-2-[[(1S)-1-phenylethyl]amino]-1-cyclobuten-1-yl]amino]-2-hydroxy-N,N-dimethylbenzamide 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.
