Used primarily as an intermediate in the synthesis of pharmaceuticals and fine chemicals. Its reactivity makes it valuable in forming amide and ester bonds, especially in the development of active pharmaceutical ingredients (APIs). Commonly employed in the preparation of benzodiazepine derivatives and other heterocyclic compounds with biological activity. Also utilized in organic synthesis for introducing the 2,3-dimethoxybenzoyl group, which can act as a protecting group or modify solubility and stability in complex molecules. Preferred in reactions where controlled acylation is required due to its selective reactivity.
