35444-44-1 6-Methoxy-6-oxohexanoyl chloride Methyl 5-(chloroformyl)valerate Methyl 6-chloro-6-oxocaproate methyl 6-chloro-6-oxohexanoate (CAS 35444-44-1) is a high-purity analytical reference standard with the molecular formula C7H11ClO3 and a molecular weight of 178.61 g/mol.
Based on its molecular formula C7H11ClO3, 35444-44-1 6-Methoxy-6-oxohexanoyl chloride Methyl 5-(chloroformyl)valerate Methyl 6-chloro-6-oxocaproate methyl 6-chloro-6-oxohexanoate contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 178.61 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
