Chemical Structure

Dexmedetomidine Impurity N1 CAS 33016-47-6 chemical structure

Description

The occurrence of Dexmedetomidine Impurity N1 is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Dexmedetomidine Impurity N1 (CAS 33016-47-6) is a certified pharmaceutical impurity reference standard with the molecular formula C23H18N2O and a molecular weight of 338.40 g/mol.

The molecular framework of Dexmedetomidine Impurity N1 (C23H18N2O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

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.
