Chemical Structure
Description
The occurrence of ethyl 2-chloro-5-methyl-3-oxohexanoate 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-chloro-5-methyl-3-oxohexanoate (CAS 1033707-35-5) is a high-purity analytical reference standard with the molecular formula C9H15ClO3 and a molecular weight of 206.67 g/mol.
The molecular framework of ethyl 2-chloro-5-methyl-3-oxohexanoate (C9H15ClO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), ethyl 2-chloro-5-methyl-3-oxohexanoate 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.
