3-Bromo-[1,1'-biphenyl]-4,4'-diamine CAS 108238-11-5

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]-4,4'-diamine.

CATO supplies 3-Bromo-[1,1'-biphenyl]-4,4'-diamine (CAS 108238-11-5), a certified reference material (molecular formula C12H11BrN2, MW 263.13 g/mol) for analytical method development and quality control.

The molecular framework of 3-Bromo-[1,1'-biphenyl]-4,4'-diamine (C12H11BrN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. 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.

As a certified reference material (CRM), 3-Bromo-[1,1'-biphenyl]-4,4'-diamine 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.
