Description

Compared with other compounds in its class, the molecular weight of 266.25 g/mol gives 4-(Benzo[1,3]dioxol-5-yloxy)-3-oxo-pentanoic acid methyl ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-(Benzo[1,3]dioxol-5-yloxy)-3-oxo-pentanoic acid methyl ester (CAS 1229623-65-7), molecular formula C13H14O6 and molecular weight 266.25 g/mol, is a CATO reference standard with documented purity and traceability.

4-(Benzo[1,3]dioxol-5-yloxy)-3-oxo-pentanoic acid methyl ester (C13H14O6) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
