951889-34-2 Ethyl 5-[3,4-(Ethylenedioxy)phenyl]-5-oxovalerate MFCD07782908 CAS 951889-34-2

Description

951889-34-2 Ethyl 5-[3,4-(Ethylenedioxy)phenyl]-5-oxovalerate MFCD07782908 (CAS 951889-34-2), molecular formula C15H18O5 and molecular weight 278.30 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 951889-34-2 Ethyl 5-[3,4-(Ethylenedioxy)phenyl]-5-oxovalerate MFCD07782908 (C15H18O5) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 278.30 g/mol, it falls into the medium-molecular-weight range. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
