A chemical intermediate is a molecular entity that is formed from the reactants, and it further reacts to give the observed products of a chemical reaction. So intermediate is not the end-product. It can help improving the properties of final products and the efficiency of production processes.

Intermediates are widely used in various chemical syntheses for the production of chemicals. These are used as starting materials for coatings, plastics, pharmaceuticals, textile fibers, rubber adhesives, detergents and pesticides, and also used in the production of numerous dyes, such as leather dyes, textiles dyes, etc.
