Methyl 6-chloro-5-oxoheptanoate (CAS 344294-91-3) is a high-purity analytical reference standard with the molecular formula C8H13ClO3 and a molecular weight of 192.64 g/mol.
Methyl 6-chloro-5-oxoheptanoate (C8H13ClO3) 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.
As a certified reference material (CRM), Methyl 6-chloro-5-oxoheptanoate 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.
