General description

2-Nitrobenzaldehyde semicarbazone is a semicarbazone derivative of 2-Nitrobenzaldehyde.

Application

2-Nitrobenzaldehyde semicarbazone (2-NBA-SC) may be used as an analytical reference standard for the determination of 2-NBA-SC in:
  • Animal muscle tissues by solid-phase extraction (SPE) and high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) equipped with electrospray ionization (ESI) source and multiple reaction monitoring (MRM) detection.
  • Milk of dairy cows by LC-MS/MS with selected reaction monitoring (SRM) detection.
  • Azodicarbonamide-treated flour samples by isotope dilution liquid chromatography coupled to ESI-LC-MS/MS.
  • Shrimp dosed with nitrofurans by ESI-LC-MS/MS with SRM detection.

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Semicarbazide was previously found in foods that were in contact with rubber gaskets foamed at high temperatures with a blowing agent azodicarbonamide. Because azodicarbonamide is an approved flour additive in certain countries, we set out to ascertain if semicarbazide is
