Aspirin/ Asprine/ acetylsalicylic acid/ C9H8O4/50-

AspirinAspirin, also known as acetylsalicylic acid is a salicylate drug, often used as an analgesic to relieve minor aches and pains, as an antipyretic to reduce fever, and as an anti-inflammatory medication.Aspirin also has an antiplatelet effect by inhibiting the production of thromboxane, which under normal circumstances binds platelet molecules together to create a patch over damage of the walls within blood vessels. Because the platelet patch can become too large and also block blood flow, locally and downstream, aspirin is also used long-term, at low doses, to help prevent heart attacks, strokes, and blood clot formation in people at high risk for developing blood clots. It has also been established that low doses of aspirin may be given immediately after a heart attack to reduce the risk of another heart attack or of the death of cardiac tissue.ITEMSSTANDARDRESULTSCharacteristicsWhite crystal or crystalline powderMeet the requirementIdentificationA violet-red color is producedGives positive reactionInfrared absorptionAccording with IR reference spectrumMeets the requirementsLoss on drying≤0.5%°0.26%Readily carbonizable substanceno more color than M.F.Qno more color than M.F.QResidue on ignition≤0.05%0.02%Substances insoluble in sodium carbonateThe solution is clearClearChloride≤0.014%<0.014%Sulfate≤0.04%<0.014%Heavy metals≤10ppm<10ppmFree salicylic acid≤0.1%<0.1%Organic volatile impuritiesMeets the requirementMeets the requirementAssayContains C9H8O499.5%-101.0%99.80%
