Drug impurity separation, preparation and structure confirmation service
Impurities in drugs are closely related to the quality, safety and stability of drugs. The preparation and structure confirmation of impurities in drugs can help us understand the ways of impurities and provide a basis for the improvement of production process. Therefore, the preparation and separation of impurities is of great significance to drug research and development.
However, the content of impurities in the drug is low, the source is wide, and the structure is mostly similar to the principal component. What technology can be used to separate and purify all impurities in the drug one by one and quickly? What techniques and methods are used to confirm the structure of these impurities? This is the difficulty and challenge faced by many pharmaceutical units, especially the pharmaceutical enterprises of plant medicine and Chinese patent medicine.
Based on such needs, the company has launched drug impurity separation and purification services. Relying on nuclear magnetic resonance, mass spectrometry and other equipment and technologies, the company can quickly identify the structure of the separated compounds, so as to meet the needs of customers.
