Analytes - aspirin (acetylsalicylic acid)

aspirin (acetylsalicylic acid): CAS No. 50-78-2, C9H8O4, molecular weight 180.15, melting point 135°C, density 1.40gm/mL, vapor pressure 0.00mm Hg at 25°C, slightly water soluble is a white crystalline solid. It is the most widely used over the counter drug and is used as a non-steroidal anti-inflammatory agent, a cyclooxygenase inhibitor, a fibrinolytic agent; a platelet aggregation inhibitor and as an analgesic for the nonspecific relief of certain types of pain due to headache, arthritis, dysmenorrhea, neuralgia and myalgia. Because it inhibits platelet function, it has been used prophylactically to reduce the incidence of myocardial infarction and transcient ischemic attacks. In gout and in acute rheumatic fever, the salicylates, including asprin, have a fairly specific action. It is most frequently measured in blood plasma, urine and commercial preparations using reversed phase HPLC.
