Cinacalcet Impurity 18 CAS 191155-81-4

Description

Compared with other compounds in its class, the molecular weight of 204.19 g/mol gives Cinacalcet Impurity 18 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Cinacalcet Impurity 18 (CAS 191155-81-4) is a certified pharmaceutical impurity reference standard with the molecular formula C10H11F3O and a molecular weight of 204.19 g/mol.

Based on its molecular formula C10H11F3O, Cinacalcet Impurity 18 contains a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 204.19 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.

CATO manufactures Cinacalcet Impurity 18 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
