Chemical Structure

Ethyl 1-methoxy-3-oxocyclobutanecarboxylate CAS 2133403-04-8 chemical structure

Description

Ethyl 1-methoxy-3-oxocyclobutanecarboxylate (C8H12O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

Ethyl 1-methoxy-3-oxocyclobutanecarboxylate (CAS 2133403-04-8), molecular formula C8H12O4 and molecular weight 172.18 g/mol, is a CATO reference standard with documented purity and traceability.

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.
