CATO supplies Methyl 3-Chloro-4-fluorobenzoate (CAS 234082-35-0), a certified reference material (molecular formula C8H6ClFO2, MW 188.58 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 3-Chloro-4-fluorobenzoate (C8H6ClFO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
