The emergence of specialty APIs also reflects the diversification within the pharmaceutical industry. Drugs produced from specialty APIs are often used for treating rare diseases or specific conditions and can be quite complex. The production of these APIs requires specialized facilities, and companies often invest heavily in research and development to bring these innovative products to market. For example, Sofosbuvir, an API used in the treatment of Hepatitis C, is an important specialty API that has revolutionized the management of this viral infection.
Ensuring the microbiological quality of water is essential, especially in industries like food and beverage, pharmaceutical, and cooling water systems. Disinfectants such as chlorine, ozone, and ultraviolet light are commonly used to eliminate harmful microorganisms. Biocides are used to control biological growth in systems like cooling towers and membrane processes, preventing fouling and contamination.
Another significant additive is corrosion inhibitors. Corrosion is a common problem in chilled water systems due to the presence of metals like copper and steel. Over time, these metals can corrode, leading to leaks and lower system efficiency. Chemicals such as sodium nitrite, sodium molybdate, and organic inhibitors like azoles are often used to provide a protective layer on metal surfaces, reducing the rate of oxidation and extending the lifespan of the equipment.
