General description

1-Pyrenebutyric hydrazide (PBH) finds biological/medical applications in the detection, labeling, and quantification of biological carbonyl compounds including aldehydes and/or ketones and carboxylic acids. It is also industrially used in chemo-sensor materials, lubricants, etc.


1-Pyrenebutyric hydrazide may be used as a fluorescence derivatization reagent in the following:
  • Determination of succinylacetone (SA) in urine samples of hepatorenal tyrosinemia patients using high-pressure liquid chromatography with fluorescence detection (HPLC-FLD).
  • Determination of glutaric and 3-hydroxyglutaric acids in urine of glutaric acidemia type I patients using HPLC technique with intramolecular excimer-forming fluorescence derivatization.

In the present work, a rapid and novel method of on-target plate derivatization of keratan sulfate (KS) oligosaccharides for subsequent analysis by matrix-assisted laser desorption and ionization (MALDI) mass spectrometry is described. MALDI-(time-of-flight)-TOF spectra of labeled KS oligosaccharides revealed that...
