Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 258.24 g/mol gives Methyl 2-fluoro-4-(4-formylphenyl)benzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Methyl 2-fluoro-4-(4-formylphenyl)benzoate (CAS 1820673-58-2), molecular formula C15H11FO3 and molecular weight 258.24 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Methyl 2-fluoro-4-(4-formylphenyl)benzoate (C15H11FO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 258.24 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
