2,2′-Dibromo-5,5′-diiodo-1,1′-biphenyl CAS 852139-02-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2′-Dibromo-5,5′-diiodo-1,1′-biphenyl.

2,2′-Dibromo-5,5′-diiodo-1,1′-biphenyl (CAS 852139-02-7) is a high-purity analytical reference standard with the molecular formula C12H6Br2I2 and a molecular weight of 563.79 g/mol.

The molecular framework of 2,2′-Dibromo-5,5′-diiodo-1,1′-biphenyl (C12H6Br2I2) is characterized by bromine/iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

CATO manufactures 2,2′-Dibromo-5,5′-diiodo-1,1′-biphenyl under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
