General description

4,4′-Methylene-bis(2-chloroaniline) is an azo dye metabolite that is deemed toxic to the environment.

Application

4,4′-Methylene-bis(2-chloroaniline) may be used as an analytical reference standard for the determination of 4,4′-methylene-bis(2-chloroaniline) in:
  • Urine samples by high performance liquid chromatography (HPLC).
  • Textile samples by HPLC coupled to tandem mass spectrometry (MS/MS) equipped with multiple reaction monitoring (MRM) mode of detection.
  • Plastic multilayer food packaging materials by LC-Orbitrap-full scan-high resolution mass spectrometry (HRMS) equipped with electrospray ionization (ESI) source.
