Chemical Structure

Carteolol Impurity 23 CAS 2096457-13-3 chemical structure

Description

The occurrence of Carteolol Impurity 23 is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Carteolol Impurity 23 (CAS 2096457-13-3) is a certified pharmaceutical impurity reference standard with the molecular formula C6H10N2 and a molecular weight of 110.16 g/mol.

Based on its molecular formula C6H10N2, Carteolol Impurity 23 contains a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 110.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), Carteolol Impurity 23 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
