Chemical Structure

Urapidil Impurity 30 CAS 817-09-4 chemical structure

Description

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

Urapidil Impurity 30 (CAS 817-09-4) is a certified pharmaceutical impurity reference standard with the molecular formula C6H12Cl3NHCl and a molecular weight of 240.98 g/mol.

Structurally, Urapidil Impurity 30 (C6H12Cl3NHCl) contains chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of -1.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 240.98 g/mol, it falls into the medium-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.

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.
