Application

O-(2,3,4,5,6-Pentafluorobenzyl)hydroxylamine hydrochloride is used:
  • In the preparation of oximes of steroids-bearing keto group.
  • As a derivatization reagent in the determination of thromboxane B2, prostaglandins, amygdalin, and a variety of aldehydes, ketones, and acids.
It is a versatile reagent used for the detection of carbonyl-containing compounds by GC, GC-MS, and other methods.

This work presents a thorough study of some aspects critical to the quantitative performance of methods for the determination of volatile aldehydes previously derivatized to pentafluorobenzyl hydroxylamine oximes. The conclusions of the study are further applied to the validation of

A central paradigm in the field of lymphocyte biology asserts that replicatively senescent memory T cells express the carbohydrate epitope CD57. These cells nonetheless accumulate with age and expand numerically in response to persistent antigenic stimulation. Here, we use in vivo deuterium

A new, fast, sensitive, and solventless extraction technique was developed in order to analyze beer carbonyl compounds. The method was based on solid-phase microextraction with on-fiber derivatization. A derivatization agent, O-(2,3,4,5,6-pentafluorobenzyl)hydroxylamine (PFBOA), was absorbed onto a divinyl benzene/poly(dimethylsiloxane) 65-microm fiber

To avoid microbiological decay pool water is disinfected, a procedure which results into a lot of disinfection by-products, like carbonyl compounds, as well as a large number of others. The carbonyl compounds dissolved in pool water were derivatisized with O-(2,3,4,5,6-pentafluorobenzyl)hydroxyamine

A simple, rapid, sensitive, and solvent-free method was developed for determination of plant-signalling compounds, the three C6-aldehydes hexanal, (Z)-3-hexenal, and (E)-2-hexenal, in tomato plant emission by gas chromatography-mass spectrometry (GC-MS) and solid-phase microextraction (SPME) with on-fiber derivatization. In this method
