Habeprazole

Rabeprazole, also known by the trade names Pariet and the development codes E-3810 and LY-307640, is a proton pump inhibitor (PPI) belonging to the benzimidazole class. It carries CAS number 117976-89-3 and molecular formula C18H21N3O3S. No E-code designation applies to this substance.

In pharmaceutical manufacturing, rabeprazole serves as the active pharmaceutical ingredient in formulations targeting acid-related gastrointestinal disorders, including gastroesophageal reflux disease and peptic ulcers. It functions by irreversibly binding to the hydrogen-potassium ATPase enzyme in gastric parietal cells, blocking the final step of acid secretion. It is also used as a reference standard in analytical method development and bioequivalence studies.

This material is supplied as a pharmaceutical-grade solid intended for use in regulated drug product manufacturing. Compliance with Ph.Eur. monograph specifications is the applicable quality benchmark for API procurement. Buyers should confirm REACH registration status and GMP documentation requirements with the supplier prior to ordering.
