Chemical Structure
Description
The occurrence of 4-Bromo-3-(trifluoromethyl)-1,1'-biphenyl is closely related to fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Bromo-3-(trifluoromethyl)-1,1'-biphenyl (CAS 876758-59-7) is a high-purity analytical reference standard with the molecular formula C13H8BrF3 and a molecular weight of 301.10 g/mol.
Structurally, 4-Bromo-3-(trifluoromethyl)-1,1'-biphenyl (C13H8BrF3) contains fluorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 301.10 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-Bromo-3-(trifluoromethyl)-1,1'-biphenyl 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.
