Assay (purity): ≥99% (extra pure grade).
Physical Appearance: White, crystalline powder or almost white crystals.
Density: 1.40 g/cm³.
Melting Point: 134–136°C (lit.), typically about 136°C.
Boiling Point: ~140°C (decomposes on boiling).
Solubility: 3–10 mg/mL in water at 25°C, freely soluble in ethanol and decomposes in aqueous base.
Loss on Drying: ≤0.5%.
Heavy Metals: ≤10 ppm.
Odor: Odorless or nearly odorless.
Uses and Applications
Pharmaceuticals: Used primarily as an analgesic (pain reliever), antipyretic (fever reducer), and anti-inflammatory drug in medicines and formulations.
Research and Analysis: Utilized in laboratories for synthesis, purity analysis, and chemical demonstrations.
Cardiovascular Medicine: Low-dose formulations are prescribed to prevent blood clots, heart attacks, and strokes.
Veterinary Medicine: Sometimes administered to dogs and other animals for pain and inflammation under veterinary supervision.
Safety and Handling
Harmful if swallowed and may cause irritation; handled with personal protective equipment in laboratory settings.
Store in a cool, dry place, protected from moisture and direct sunlight, in tightly sealed containers.
Stable in dry air, but hydrolyzes gradually in moisture, releasing acetic acid and salicylic acid.
