Chemical Structure
Description
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.
Cinacalcet Impurity 19 (CAS 1813-96-3), molecular formula C10H9F3 and molecular weight 186.17 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine substitution, an aromatic ring system, Cinacalcet Impurity 19 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 186.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
