2.  Impurities analysis

SINOPEG uses modern separation and analysis methods to provide impurity analysis of chemically synthesized API and their preparations for the detection and quantitative determination of impurities. Impurities are key quality attributes of drugs, which can affect the safety and effectiveness of products. These impurities may be identified or unidentified, volatile or non-volatile, including starting materials, byproducts, intermediates, degradation products, reagents, coordination bodies and catalysts, etc.  

For new drugs, impurities brought into the production process or raw materials or generated during the storage process can be detected.  For modified production and generic drugs, if the drug manufacturer changes the production process or introduces new impurities into the raw materials and excipients, it is necessary to carry out impurity analysis again, revise the original quality standard, and apply for approval to the drug regulatory department according to law.  SINOPEG provides scientific and impartial impurity analysis for customers with professional and rigorous scientific spirit, and has been well received by customers for its high-end technical level and high-quality technical service.
