Compared with other compounds in its class, the molecular weight of 186.20 g/mol gives 4-Difluoromethyl-2,5-dimethylanisole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Difluoromethyl-2,5-dimethylanisole (CAS 1803785-33-2), molecular formula C10H12F2O and molecular weight 186.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Difluoromethyl-2,5-dimethylanisole (C10H12F2O) is characterized by a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
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.
