O-(2,3,4,5,6-PENTAFLUOROBENZYL)HYDROXYLAMINE HYDROCHLORIDE Chemical Properties,Uses,Production

Chemical Properties

White powder

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.

Uses

PFBHA.HCl has been used for derivatization of metabolites with carbonyl groups followed by analysis via GC-MS. It has also been used in aldehyde derivatization followed by aldehydic hydrolysis using GC/MS.

Uses

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.

General Description

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

reaction suitability

reagent type: derivatization reagent
reaction type: Alkylations

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.
