After synthesis, the crude API needs to be purified to eliminate impurities and obtain the desired purity level, often 98% or higher. Common purification techniques include recrystallization, distillation, chromatography, and membrane filtration. Each technique has its advantages and is selected based on the specific characteristics of the API. The purification process is critical as impurities can significantly impact the safety and efficacy of the final pharmaceutical product.

The incorporation of fragrance into plastics is achieved through selected additives that can impart specific scents to the final products. These additives can be designed to release fragrance gradually over time, a feature particularly desirable for items such as scented candles, air fresheners, and personal care products. The process involves embedding microcapsules of fragrance within the plastic matrix, which slowly release the scent when the product is used or comes into contact with air.
