Chemical Structure

4-Bromo-2-(difluoromethyl)-1-ethoxybenzene CAS 2167992-65-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromo-2-(difluoromethyl)-1-ethoxybenzene.

CATO supplies 4-Bromo-2-(difluoromethyl)-1-ethoxybenzene (CAS 2167992-65-4), a certified reference material (molecular formula C9H9BrF2O, MW 251.07 g/mol) for analytical method development and quality control.

The molecular framework of 4-Bromo-2-(difluoromethyl)-1-ethoxybenzene (C9H9BrF2O) is characterized by a hydroxyl group, an ether linkage, fluorine/bromine 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
