Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3'-Bromo-[1,1'-biphenyl]-4-ol.
3'-Bromo-[1,1'-biphenyl]-4-ol (CAS 70066-67-0), molecular formula C12H9BrO and molecular weight 249.10 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3'-Bromo-[1,1'-biphenyl]-4-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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
