General description

α-tert-Butyl-β-(4-chlorobenzyl)-1H-1,2,4-triazole-1-ethanol is a known plant growth regulator which is utilized to inhibit the alternate bearing habit of mango (Mangifera indica L.).

Application

α-tert-Butyl-β-(4-chlorobenzyl)-1H-1,2,4-triazole-1-ethanol may be used as a reference standard for the determination of the analyte in:
  • Apple juice samples by matrix solid-phase dispersion (MSPD) and gas chromatography-mass selective detection (GC-MSD) with electron impact (EI) ionization.
  • Processed fruits and vegetables by miniaturized extraction-partition and liquid chromatography-electrospray tandem mass spectrometry (LC-ESI-MS/MS) equipped with multiple reaction monitoring (MRM) detection.
  • Crops and soya grains by LC-ESI-MS/MS with MRM detection.
