Used primarily in organic synthesis, 3-Chlorobenzhydrazide serves as a key intermediate in the production of various pharmaceuticals and agrochemicals. It is often employed in the development of compounds with potential therapeutic properties, such as antimicrobial or anti-inflammatory agents. Additionally, it plays a role in the synthesis of dyes and pigments due to its ability to form stable derivatives. Its reactivity with carbonyl compounds makes it valuable in the creation of hydrazones, which are useful in analytical chemistry for detecting and quantifying aldehydes and ketones.
