Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 206.67 g/mol gives Ethyl 3-chloro-5-methyl-2-oxohexanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ethyl 3-chloro-5-methyl-2-oxohexanoate (CAS 111055-64-2), a certified reference material (molecular formula C9H15ClO3, MW 206.67 g/mol) for analytical method development and quality control.
Ethyl 3-chloro-5-methyl-2-oxohexanoate (C9H15ClO3) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
