Product Description of Phenylbutazone Sodium CAS#129-18-0
Phenylbutazone sodium is a white to off-white crystalline powder with a molecular formula of C₁₉H₁₉N₂NaO₂ and a molecular weight of 330.36. As the sodium salt form of phenylbutazone, it belongs to the non-steroidal anti-inflammatory drug (NSAID) class and is widely used for its anti-inflammatory, analgesic and antipyretic effects.
The product has a melting point of approximately 105–107 °C and dissolves readily in water and ethanol owing to its salt nature. It exhibits good chemical stability when stored properly, but should be kept in a tightly sealed, dry and cool environment, protected from light and moisture, to preserve its purity and pharmacological activity during storage and transportation.
