Description
As a certified reference material (CRM), 3-bromo-5-fluoroanisole 496052-50-7 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
3-bromo-5-fluoroanisole 496052-50-7 (CAS 496052-50-7) is a high-purity analytical reference standard with the molecular formula C7H6BrFO and a molecular weight of 205.02 g/mol.
Structurally, 3-bromo-5-fluoroanisole 496052-50-7 (C7H6BrFO) contains a hydroxyl group, an ether linkage, fluorine/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 205.02 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.
