Chemical Structure

2-Bromo-4,5-difluorophenol CAS 166281-37-4 chemical structure

Description

2-Bromo-4,5-difluorophenol (CAS 166281-37-4) is a high-purity analytical reference standard with the molecular formula C6H9BrF2O and a molecular weight of 215.04 g/mol.

2-Bromo-4,5-difluorophenol (C6H9BrF2O) contains a hydroxyl group, an ether linkage, fluorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
