Description

Sodium o-Acetylsalicylate is the sodium salt derivative of acetylsalicylic acid (aspirin). This compound is valued for its enhanced solubility and stability profile compared to its parent acid, making it a crucial intermediate in advanced pharmaceutical synthesis. It is primarily utilized by manufacturers in the pharmaceutical and fine chemical industries for the production of analgesic and anti-inflammatory APIs, as well as in research and development for novel drug formulations.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of salicylate-based active pharmaceutical ingredients (APIs).
• Analgesic & Anti-inflammatory Drug Production: Used in the manufacture of modified-release and soluble aspirin formulations.
• Biochemical Research: Serves as a substrate or standard in enzymatic studies related to cyclooxygenase (COX) pathways.
• Fine Chemical Synthesis: An intermediate for producing other specialized salicylate derivatives and esters.
• Veterinary Pharmaceuticals: Employed in the development of soluble pain management medications for animal health.
