Salicylaldehyde is widely used in organic synthesis as a precursor for the production of various chemicals, including pharmaceuticals, dyes, and fragrances. It serves as a key intermediate in the synthesis of coumarin, which is employed in perfumes and flavoring agents. Additionally, it is utilized in the preparation of salicylaldoxime, a compound important in metal extraction and separation processes. In the pharmaceutical industry, salicylaldehyde is a building block for creating anti-inflammatory and antimicrobial agents. It also finds application in the production of agrochemicals, such as pesticides and herbicides, due to its reactive aldehyde group. Furthermore, it is used in analytical chemistry as a reagent for detecting and quantifying metal ions.
