Br-BT-CHO, namely 7-Bromobenzo[c][1,2,5]thiadiazole-4-carbaldehyde, is a benzothiadiazole derivative with both bromine and aldehyde functiona groups. Br-BT-CHO can be used as intermediate for further either carbon-carbon single bond (C-C) via Stille coupling, or double bond (C=C) formation via Aldol condensation reactions.
