Chemical Structure
Description
The occurrence of 1-(4-Fluoro-3-methylphenyl)-3-methylbutan-1-one is closely related to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(4-Fluoro-3-methylphenyl)-3-methylbutan-1-one (CAS 1175916-26-3), molecular formula C12H15FO and molecular weight 194.25 g/mol, is a CATO reference standard with documented purity and traceability.
1-(4-Fluoro-3-methylphenyl)-3-methylbutan-1-one (C12H15FO) contains a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
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.
