Chemical Structure
Description
Structurally, 5-Bromo-2,4-difluoro-3-methylbenzaldehyde (C8H5BrF2O) contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 235.03 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).
5-Bromo-2,4-difluoro-3-methylbenzaldehyde (CAS 1378865-38-3) is a high-purity analytical reference standard with the molecular formula C8H5BrF2O and a molecular weight of 235.03 g/mol.
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.
