Applications

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.

Notes

Store in a cool, dry, well-ventilated area. Incompatible with bases and oxidizing agents. Store at 4°C. Protected from moisture.
