Chemical Structure

Tolvaptan Impurity 104 CAS CATO-C4X-1955104 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 528.92 g/mol gives Tolvaptan Impurity 104 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Tolvaptan Impurity 104 (CAS CATO-C4X-1955104) is a certified pharmaceutical impurity reference standard with the molecular formula C26H26ClN2O6P and a molecular weight of 528.92 g/mol.

Structurally, Tolvaptan Impurity 104 (C26H26ClN2O6P) contains a steroid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.5, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 528.92 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

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.
