Description

(S)-Lansoprazole CAS NO 138530-95-7 is the single enantiomer of the proton pump inhibitor lansoprazole, representing a high-purity active pharmaceutical ingredient (API) with targeted therapeutic potential. This compound matters for its role in developing more potent and selective gastric acid suppression therapies with potentially improved pharmacokinetic profiles. Pharmaceutical R&D teams and manufacturers of enantiomerically pure drugs need it for advanced formulation development and clinical studies targeting acid-related disorders.

Application

• Primary active pharmaceutical ingredient (API) in the development of enantiomerically pure proton pump inhibitor medications.
• Key intermediate for advanced pharmaceutical research into gastroesophageal reflux disease (GERD) and peptic ulcer treatments.
• Reference standard for analytical method development and quality control in pharmaceutical laboratories.
• Building block for chemical synthesis and pharmacological studies exploring the (S)-enantiomer's specific bioactivity.
• Material for formulation studies aimed at creating improved drug delivery systems for acid suppression.
