Final answer:
To verify the purity of aspirin powder, the QC department should conduct various tests such as spectroscopy, chromatography, mass spectrometry, titration, percent composition analysis, content uniformity, and melting point analysis.
Step-by-step explanation:
To ensure the aspirin powder received from China is pure, a series of quality control tests must be conducted in the Quality Control (QC) department of a pharmaceutical company like Julphar. As part of the QC measures, one would typically carry out both qualitative and quantitative analytical techniques. These would include spectroscopy (such as FTIR to confirm the molecular structure), chromatography (like HPLC to assess purity and identify contaminants), mass spectrometry, and titration to determine the exact amount of the active pharmaceutical ingredient (API).
One can analyze the content for the presence of intended reactants and any unwanted by-products such as salicylic acid. Moreover, determination of the percent composition of the aspirin can also be helpful to support the purity level. Along with this, considering the stability of the compound, one should perform a content uniformity test to ensure that each batch of the product has a consistent amount of the API. Finally, physical tests like melting point analysis would also be necessary as impurities can affect the melting point of a substance.
It is crucial to ensure the aspirin meets the regulatory standards for purity, as impurities can affect the structure, properties, and efficacy of the finished pharmaceutical product. Julphar's QC department is responsible for maintaining the safety and effectiveness of the drug by confirming that it complies with predefined specifications.
