In Pharmaceutical and Chemical Industries

The pharmaceutical and chemical industries deal with a wide variety of raw materials (excipients) and finished products, involving complex and diverse production processes. Many pharmaceuticals exhibit either complex chemical structures or minimal chemical differences among them, making conventional methods such as color reactions, precipitation, crystallization, or UV-VIS often insufficient for adequate differentiation. Infrared spectroscopy, with its high specificity, is a widely employed method in the qualitative analysis of organic compounds. In pharmaceutical inspection,infrared spectroscopy is frequently used in conjunction with other analytical methods, serving as a crucial means of identifying organic drugs.
