Chemical Structure
Description
The occurrence of Methyl 7,7,7-trifluoro-6-oxoheptanoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Methyl 7,7,7-trifluoro-6-oxoheptanoate (CAS 141023-00-9), molecular formula C8H11F3O3 and molecular weight 212.17 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, Methyl 7,7,7-trifluoro-6-oxoheptanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 212.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
