Description

(R)-Omeprazole Sodium Salt is the single enantiomer sodium salt form of the widely used proton pump inhibitor, omeprazole. This high-purity chiral intermediate is critical for the development and manufacturing of enantiomerically pure active pharmaceutical ingredients (APIs) targeting gastric acid-related disorders. It is primarily utilized by pharmaceutical R&D laboratories and manufacturers specializing in advanced, stereoselective synthesis.

Application

• Pharmaceutical Intermediate: Key chiral building block for the synthesis of enantiopure proton pump inhibitor drugs.
• Active Pharmaceutical Ingredient (API) Development: Used in research and production of novel, single-isomer gastrointestinal therapeutics.
• Pharmacological Research: Serves as a reference standard and material for studying the specific biological activity of the (R)-enantiomer.
• Process Chemistry & Scale-Up: Employed in optimizing and scaling stereospecific synthetic routes under GMP conditions.
• Analytical Standard: Used for method development, validation, and quality control (HPLC, Chiral Chromatography) in pharmaceutical analysis.
