Description

Pirprofen is a non-steroidal anti-inflammatory drug (NSAID) belonging to the propionic acid derivative class, identified by the CAS registry number 31793-07-4. It functions as a potent cyclooxygenase inhibitor, offering significant value in pharmaceutical research and development for its anti-inflammatory and analgesic properties. This compound is primarily utilized by pharmaceutical manufacturers and research institutions engaged in the development of novel therapeutic agents for pain and inflammation management.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs) for anti-inflammatory medications.
• Biochemical Research: Used as a reference standard or tool compound in pharmacological studies to investigate COX enzyme inhibition mechanisms.
• Analytical Standard: Serves as a high-purity standard for quality control and method development in analytical laboratories (HPLC, LC-MS).
• Preclinical Development: Employed in animal model studies to evaluate efficacy, pharmacokinetics, and safety profiles of new NSAID formulations.
• Academic Research: Utilized in university and institutional labs for studying the structure-activity relationships (SAR) of propionic acid derivatives.
