Chemical Structure
Description
5-[2-(4-Methoxybenzoyl)cyclopropyl]-2H-1,3-benzodioxole (CAS 338749-14-7), molecular formula C18H16O4 and molecular weight 296.32 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, 5-[2-(4-Methoxybenzoyl)cyclopropyl]-2H-1,3-benzodioxole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 296.32 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.
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.
