Applicazioni

2-Bromo-5-fluorobenzaldehyde is used as a precursor for the synthesis of 5-fluoro-3-substituted benzoxaboroles, which is used in material science as molecular receptors, building block in crystal engineering, as steroid conjugates for molecular imprinting , dyes and biosensors of alpha hydroxyl carboxylic acids. It is also used in the synthesis of 5-arylindazolo[3,2-b]quinazolin-7(5H)-one by reacting with 2-amino-N'-arylbenzohydrazide in the presence of Copper(I) bromide by the Ullmann-type reaction.

Note

Air sensitive. Keep container tightly closed in a cool, dry and well-ventilated place.
