Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 241.46 g/mol gives 1-Bromo-3-chloro-5-(difluoromethyl)benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-Bromo-3-chloro-5-(difluoromethyl)benzene (CAS 1261580-23-7), a certified reference material (molecular formula C7H4BrClF2, MW 241.46 g/mol) for analytical method development and quality control.
Structurally, 1-Bromo-3-chloro-5-(difluoromethyl)benzene (C7H4BrClF2) contains fluorine/chlorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 241.46 g/mol, it falls into the medium-molecular-weight range. 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.
