Chemical Structure

Lansoprazole Impurity 49 CAS CATO-C4X-161249 chemical structure

Description

Lansoprazole Impurity 49 (CAS CATO-C4X-161249), molecular formula C22H22O2 and molecular weight 318.41 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Lansoprazole Impurity 49 (C22H22O2) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 318.41 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
