1-(4′-Sulfophenyl)-3-methyl-5-pyrazolone

Description:
1-(4′-Sulfophenyl)-3-methyl-5-pyrazolone, commonly known as Sulfopyrazone, is a chemical compound characterized by its pyrazolone structure, which includes a sulfonic acid group that enhances its solubility in water. This compound typically appears as a white to light yellow crystalline powder and is known for its analgesic and anti-inflammatory properties. It is often utilized in the pharmaceutical industry, particularly in the formulation of medications for pain relief and inflammation. The presence of the sulfonic acid group contributes to its polar nature, making it more soluble in aqueous solutions compared to non-sulfonated pyrazolones. Additionally, Sulfopyrazone exhibits a moderate melting point and is stable under standard conditions, although it should be stored away from strong oxidizing agents. Its chemical reactivity is influenced by the functional groups present, allowing for various derivatizations that can enhance its therapeutic efficacy. Overall, this compound plays a significant role in medicinal chemistry and pharmacology.
