Description

Compared with other compounds in its class, the molecular weight of 264.23 g/mol gives Ethyl 4-(Benzo[d][1,3]dioxol-5-yl)-2,4-dioxobutanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl 4-(Benzo[d][1,3]dioxol-5-yl)-2,4-dioxobutanoate (CAS 62849-03-0), molecular formula C13H12O6 and molecular weight 264.23 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Ethyl 4-(Benzo[d][1,3]dioxol-5-yl)-2,4-dioxobutanoate (C13H12O6) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 264.23 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.
