General description

2-Nitrobenzaldehyde semicarbazone is a semicarbazone derivative of 2-Nitrobenzaldehyde.[1]

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.[2]
  • Milk of dairy cows by LC-MS/MS with selected reaction monitoring (SRM) detection.[3]
  • Azodicarbonamide-treated flour samples by isotope dilution liquid chromatography coupled to ESI-LC-MS/MS.[4]
  • Shrimp dosed with nitrofurans by ESI-LC-MS/MS with SRM detection.[5]

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