Omeprazole

Omeprazole (CAS 73590-58-6) is a pharmaceutical intermediate classified under the benzimidazole family, commercially recognised under trade names including Losec, ANTRA, and Aulcer. It carries no assigned E-code and is catalogued under EC number 615-996-8 with the molecular formula C17H19N3O3S.

In pharmaceutical manufacturing, omeprazole functions as an active ingredient in proton pump inhibitor formulations, suppressing gastric acid secretion by irreversibly blocking the hydrogen-potassium ATPase enzyme in gastric parietal cells. It also demonstrates antioxidant and antimicrobial activity, making it relevant in formulation research targeting oxidative degradation pathways and microbial stability.

Omeprazole is supplied as a white crystalline solid to pharmaceutical-grade specifications aligned with Ph.Eur. and USP monographs, and is subject to REACH compliance requirements for European trade. It is classified under HS code 29333990 and is available in standard laboratory and bulk packaging formats suited to formulation and API manufacturing workflows.
