Diphenylamine is a fat-soluble organic antioxidant, widely used to control post-harvest skin scalding in apples and pears by preventing the oxidation of α-farnesene.
According to the Commission Implementing Regulation (EU) No 578/2012 of 29th June 2012, diphenylamine is not approved for use in the European Union (EU) as an active substance in the plant protection products, following the Regulation (EC) No. 1107/2009. But a default maximum residue limit of 0.05 mg/kg is allowed for its presence in the products of plant and animal origin as per the EU Reg. 2018/1515.

Application

The certified reference material (CRM) is intended to be used as a calibrant for chromatography and other analytical techniques.
Diphenylamine CRM may also be used as given below:

  • Development and validation of a gas chromatography-mass spectrometry (GC-MS) method for the simultaneous analysis of diphenylamine, tolylfluanid, propargite, and phosalone in human liver samples
  • Determination of diphenylamine residues in fruit samples after applying a combination of supercritical fluid extraction (SFE) and supramolecular solvent-based microextraction (SSME) for the extraction, followed by a determination using high-performance liquid chromatography (HPLC) with ultraviolet (UV) detection
  • Evaluate a newly designed molecularly imprinted polymer (MIP) based on β-cyclodextrin (β -CD) and graphene oxide (GO) for the determination of diphenylamine
  • Analysis of diphenylamine in apple samples using an electrochemical sensor based on phosphomolybdic acid (PMo12) and graphene oxide (GO)
  • Investigate the performance of an electrochemical sensor founded upon polymeric carbon-rich graphitic carbon nitride (C-gCN) to detect diphenylamine in apple juice samples
  • Study the determination of diphenylamine in apple and pear samples using an electrochemical sensor based on Copper@nanoporous carbon (Cu@NPC) as the electrode material

Ion Mobility: TWCCSN2 value of 135.5 Å2 [M+H]+

The collision cross section (CCS) measurement was provided by Waters Corporation, using the SYNAPT XS mass spectrometer.
For a description and overview of how ion mobility enables the measurement of the CCS of an ion visit ims.waters.com.
Further information on the SYNAPT XS mass spectrometer can be found on the IMS microsite and product webpage.

TWCCS measurements are expected to be within 2% of this reference value.
