α-Bromo-2,3,4,5,6-pentafluorotoluene Chemical Properties,Uses,Production

Chemical Properties

CLEAR COLOURLESS TO YELLOWISH LIQUID

Uses

Pentafluorobenzyl bromide (PFB-Br) is an alkylating reagent which can be used to modify hydroxyl groups, carboxyl groups, sulfhydryl groups, and amines.PFB-Br can also be used to measure nitrite and peroxynitrite.It is a versatile reagent.

Uses

2,3,4,5,6-Pentafluorobenzyl bromide is used as a reagent for derivatization of alcohols, carboxylic acids, sulfonamides for GC and polyfunctional thiols. It is used for the preparation of pentafluorobenzyl esters of organic acids for determination by capillary and GC. It is also used to derivatize N-7-substituted guanine adducts of DNA for determination by GC-electron capture-MS.

Definition

ChEBI: Pentafluorobenzyl bromide is a member of the class benzyl bromides that is benzyl bromide in which the hydrogens at positions 2, 3, 4, 5 and 6 of the phenyl ring are replaced by fluoro groups. It is a versatile derivatization agent in chromatography and mass spectrometry. It is a member of benzyl bromides and a member of fluorobenzenes.

General Description

Pentafluorobenzyl bromide (PFB-Br) is a derivatization reagent. Excess reagent may be removed by reaction with an aminophenol. It is an alkylation reagent suitable for electron capture detector (ECD) detection. It is also a lachrymator.
