[Uses]

O-(2,3,4,5,6-Pentafluorobenzyl)hydroxylamine hydrochloride is used in the preparation of oximes of steroids having keto group. It is used 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 utilized for the detection of carbonyl-containing compounds by gas chromatography (GC), gas chromatography mass spectrometry (GC-MS) and other methods. As a derivatization reagent, it is also used for EC/LC analysis of keto-steroids and carbohydrates.
[General Description]

O-(2,3,4,5,6-Pentafluorobenzyl)hydroxylamine hydrochloride (PFBHA.HCl) is a derivatizing agent.
[Purification Methods]

Recrystallise the salt from EtOH to form colourless leaflets. Drying the compound at high vacuum and elevated temperature will result in losses by sublimation.
