Description

(S)-(+)-Ketoprofen CAS NO 22161-81-5 is the pharmacologically active enantiomer of the non-steroidal anti-inflammatory drug (NSAID) ketoprofen. This high-purity chiral building block is critical for developing enantiomerically pure pharmaceuticals with enhanced efficacy and reduced side-effect profiles. It is essential for pharmaceutical R&D and manufacturing, particularly for companies specializing in advanced chiral synthesis and the production of targeted anti-inflammatory and analgesic agents.

Application

• Active Pharmaceutical Ingredient (API) for enantiomerically pure NSAID formulations.
• Chiral intermediate in advanced pharmaceutical synthesis and process development.
• Reference standard for analytical method development and quality control in pharmaceutical laboratories.
• Key starting material for research into novel COX-1 and COX-2 inhibitors.
• Building block for preclinical and clinical studies of targeted anti-inflammatory therapies.
• Used in the development of transdermal patches and other advanced drug delivery systems.

Quality Control

Our (S)-(+)-Ketoprofen is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including chiral purity assay, to ensure compliance with pharmaceutical-grade standards. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming identity, purity, and enantiomeric excess.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept tightly sealed in a dry environment away from direct light exposure to maintain stability and purity.
