Description

Dexibuprofen Lysine (Innm) is the lysine salt of the active enantiomer of ibuprofen, representing a high-purity, advanced pharmaceutical intermediate. This compound is specifically valued for its enhanced solubility and bioavailability compared to the racemic mixture, which is critical for developing more effective and efficient analgesic and anti-inflammatory formulations. It is primarily required by pharmaceutical manufacturers and R&D organizations focused on producing next-generation non-steroidal anti-inflammatory drugs (NSAIDs) and targeted pain management therapies.

Application

• Active Pharmaceutical Ingredient (API) in advanced analgesic and anti-inflammatory medications.
• Key intermediate in the synthesis of enantiomerically pure S-ibuprofen formulations.
• Research and development of novel drug delivery systems for improved solubility and absorption.
• Production of prescription and over-the-counter (OTC) pain relief products.
• Manufacturing of pharmaceutical preparations targeting arthritis, musculoskeletal pain, and post-operative inflammation.
• Reference standard in analytical laboratories for quality control and method development.
