The objective of this study was to synthesize aspirin (acetylsalicylic acid) in the laboratory and thereafter evaluate its quality in comparison to aspirin tablets marketed by two distinct pharmaceutical corporations. In an acidic environment, salicylic acid and acetic anhydride were utilized to synthesize the chemical. Then, it was cleaned up by recrystallization. We checked the product's physical qualities, such as its melting point and yield. The yield was supposed to be 11.72 g, however it was only 8.5 g, which means the percentage yield was 72.5%. This is a good outcome for a synthesis at the academic level. The melting point of the synthesized aspirin was 140 °C, which is close to the normal range of 135–136 °C. This suggests that it was really clean. The melting points of commercial aspirin from British and Egyptian companies were substantially different, though (120 °C and 220 °C). This could suggest that the aspirin is breaking down or that it has additives in it. The study highlighted how crucial quality control is in drug development and how helpful it is for students to acquire hands-on experience producing and evaluating pharmacological compounds. It also underlined how important it is to use correct analytical procedures and maintain a close eye on the conditions of synthesis. In conclusion, lab-made aspirin was just as excellent as the criteria specified by the pharmacopeia and was cleaner than certain samples sold in stores. The research demonstrates the significance of include both synthesis and analytical assessment in pharmaceutical science curricula.
