Salicylaldehyde is widely used in the synthesis of organic compounds, particularly in the production of coumarins, which are important in the fragrance and pharmaceutical industries. It serves as a key intermediate in the manufacture of agrochemicals, including pesticides and herbicides, due to its ability to form complex structures. In the field of coordination chemistry, it is utilized as a ligand to create metal complexes with various applications in catalysis and material science. Additionally, salicylaldehyde is employed in the preparation of dyes and pigments, contributing to vibrant and stable colorants for textiles and other materials. Its antimicrobial properties also make it useful in certain preservative formulations.
