Chemical Structure

Ethyl 2,2-Dichloro-3-oxobutanoate CAS 6134-66-3 chemical structure

Description

The occurrence of Ethyl 2,2-Dichloro-3-oxobutanoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl 2,2-Dichloro-3-oxobutanoate (CAS 6134-66-3) is a high-purity analytical reference standard with the molecular formula C6H8Cl2O3 and a molecular weight of 199.03 g/mol.

Ethyl 2,2-Dichloro-3-oxobutanoate (C6H8Cl2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), Ethyl 2,2-Dichloro-3-oxobutanoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
