API refers to the active substance used in the production of pharmaceutical preparations. In the supervision and inspection, attention should be paid to the stability of the API production process and the controllability of impurities. The quality of raw materials can not be guaranteed, which will directly affect the quality of subsequent drugs. We have longly carried out API testing services to help customers do a good job in API quality control.
The test items include appearance, odor and taste, melting point, solubility, drug identification, fineness, particle size, crystal type, thermal stability, adsorption, porosity, molecular weight, viscosity, fluorine content, chlorine content, nitrogen content, absorption, clarification, inorganic anion, drying weight loss, moisture, residue, metal ions, heavy metals, organic impurities, pH value, microbial detection.
