Activated carbon is used to eliminate the coloured impurities produced in the reactor during the synthesis of active pharmaceutical ingredients. Composed of porous carbonaceous material that retains undesirable molecules by adsorption, it is used to purify and decolourise the products synthesised. Activated carbon can be added directly to the reactor before being filtered, or better still, as the media in a filtering device.

Depending on their position in the devices, the filters used in the pharmaceutical industry have different roles: essential information to know: depth filtration, surface filtration, technological and regulatory aspects.

Filters used in the API manufacturing process must be compatible with all the chemicals and solvents used in the production line. If there are no contraindications, stainless steel filter bodies are preferred. However, some syntheses require the use of solvents that are not compatible with stainless steel filtration equipment. What are the alternatives?
