The Quality Standards of alpha - [2 - (diisopropylamino) ethyl] - alpha - phenyl - 2 - pyridyl acetamide are numerous. Regarding chemical purity, when seeking purity, the impurity content must be extremely low. The organic impurities, such as residual reaction raw materials, by-products, etc., should be strictly limited to maintain the high purity of the main component, usually the main component content should be more than 98%.
The amount of related substances, various isomers and degradation products should also be accurately determined and strictly controlled. For example, the proportion of isomers should not exceed a specific value to prevent affecting their pharmacological activity and safety. Degradation products, or due to light, temperature, humidity and other factors, must also be limited within the safe range.
For residual solvents, such as dichloromethane, methanol and other organic solvents, due to their potential toxicity, the residual amount must be strictly limited in accordance with relevant regulations and standards. Generally speaking, the first type of solvent should not be detected, and the second type of solvent residue must meet the established low limit standards.
