Organic intermediates refer to compounds that are involved in chemical reactions as intermediates, meaning they are formed during the course of a reaction and then further react to form the final product. These intermediates contain carbon atoms and are often utilized in organic synthesis to construct more complex organic molecules. Organic intermediates play a fundamental role in organic chemistry, serving as building blocks for the synthesis of a wide range of organic compounds, including pharmaceuticals, polymers, and agrochemicals. Examples of organic intermediates include aldehydes, ketones, esters, and halides.
