Chemical Structure
Description
The occurrence of 4'-Bromo-[1,1'-biphenyl]-2-ol is closely related to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4'-Bromo-[1,1'-biphenyl]-2-ol (CAS 21849-89-8), a certified reference material (molecular formula C12H9BrO, MW 249.10 g/mol) for analytical method development and quality control.
Structurally, 4'-Bromo-[1,1'-biphenyl]-2-ol (C12H9BrO) contains a hydroxyl group, an ether linkage, 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 249.10 g/mol, it falls into the medium-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.
