(R)-Rabeprazole Sodium Salt CAS CATO-C4X-112111

Description

Compared with other compounds in its class, the molecular weight of 382.43 g/mol gives (R)-Rabeprazole Sodium Salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(R)-Rabeprazole Sodium Salt (CAS CATO-C4X-112111) is a high-purity analytical reference standard with the molecular formula C18H21N3O3SNa and a molecular weight of 382.43 g/mol.

Based on its molecular formula C18H21N3O3SNa, (R)-Rabeprazole Sodium Salt contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 382.43 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
