Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of benzimidazole-based drugs with antiparasitic, antiviral, and anticancer properties. It serves as a building block in creating compounds that target specific enzymes and receptors in biological systems. Its structure allows for easy modification, making it valuable in medicinal chemistry for drug design and optimization. Also utilized in research settings to develop new bioactive molecules and in the preparation of fluorescent probes for biochemical assays.
