Chemical Structure

Ethyl 2-methyl-4-oxooxane-2-carboxylate CAS 141033-94-5 chemical structure

Description

Ethyl 2-methyl-4-oxooxane-2-carboxylate (CAS 141033-94-5) is a high-purity analytical reference standard with the molecular formula C9H14O4 and a molecular weight of 186.21 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Ethyl 2-methyl-4-oxooxane-2-carboxylate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 186.21 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.

CATO manufactures Ethyl 2-methyl-4-oxooxane-2-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
