Chemical Structure

Ramelteon Impurity 48 CAS CATO-C4X-262248 chemical structure

Description

The occurrence of Ramelteon Impurity 48 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ramelteon Impurity 48 (CAS CATO-C4X-262248) is a certified pharmaceutical impurity reference standard with the molecular formula C13H13NO2 and a molecular weight of 215.25 g/mol.

Based on its molecular formula C13H13NO2, Ramelteon Impurity 48 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 215.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), Ramelteon Impurity 48 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.
