Chemical Structure

(+)-Ilaprazole CAS 910664-01-6 chemical structure

Description

(+)-Ilaprazole (CAS 910664-01-6) is a high-purity analytical reference standard with the molecular formula C19H18N4O2S and a molecular weight of 366.44 g/mol.

(+)-Ilaprazole (C19H18N4O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
