Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 158.15 g/mol gives 3,4-Difluorophenetole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3,4-Difluorophenetole (CAS 163848-46-2), a certified reference material (molecular formula C8H8F2O, MW 158.15 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 3,4-Difluorophenetole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 158.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
