General description

Ethyl 3-aminobenzoate methanesulfonate salt is a synthetic benzocaine derivative that belongs to the class of ester-type anaesthetics, widely used in aquacultures.

Application

Ethyl 3-aminobenzoate methanesulfonate analytical standard can be used as follows:

  • Preparation of an anti-TMS monoclonal antibody (mAb) for the analysis of tricaine in fish samples using a lateral-flow immunochromatographic strip (LF-ICS) method
  • Modified QuEChERS-based sample extraction of tricaine methanesulfonate from blood, muscle, and liver samples obtained from carp fish for its analysis by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS)
  • Multi-residue detection of tricaine mesylate and malachite green in aquaculture water, fish, and shrimp samples using tricolor immunochromatographic test strip with double test lines (TS-DTL)
  • Analysis of water samples for MS-222 using solid phase extraction for sample treatment and liquid chromatography/tandem mass spectrometry (LC-MS/MS) for determination
