Intermediates in organic synthesis refer to molecules that have not yet been fully integrated into the desired molecules in organic chemical synthesis. They are only an intermediate state of the molecule. They may be either an ionic group or a relatively stable macromolecule with an external non-electric property. After being synthesized, it can become a stable compound. In short, Organic Intermediates are intermediates used in chemical synthesis, including alcohols, phenols, benzene, alkenes, ketones, amines, anhydrides and so on. Organic intermediates can be used as Pharmaceutical Intermediates, dye intermediates and Material Intermediates. Organic intermediates are mainly used in the development of organic synthetic chemical products, especially in medicine, pesticides, dyes, organic pigments, photosensitive materials and so on.
