4,4’’-Diamino-3,3’’,5,5’’-tetrabromobiphenyl CAS 62477-23-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,4’’-Diamino-3,3’’,5,5’’-tetrabromobiphenyl.

CATO supplies 4,4’’-Diamino-3,3’’,5,5’’-tetrabromobiphenyl (CAS 62477-23-0), a certified reference material (molecular formula C12H8Br4N2, MW 499.82 g/mol) for analytical method development and quality control.

The molecular framework of 4,4’’-Diamino-3,3’’,5,5’’-tetrabromobiphenyl (C12H8Br4N2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
