2,3,4,5,6-Pentafluorobenzyl bromide, 97%

Description

CAS: 1765-40-8 | C7H2BrF5 | 260.989 g/mol

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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
