5-Bromo-2-chlorobenzaldehyde is an aromatic aldehyde where a formyl group (–CHO) is attached to a benzene ring substituted with bromine at the 5-position and chlorine at the 2-position. It is commonly used as a synthetic intermediate in pharmaceutical chemistry, including in the synthesis of Empagliflozin, and can also appear as a process-related impurity. The halogen substituents influence its chemical reactivity in subsequent reactions.
