Flunarizine Impurity 15 CAS 365-20-8 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Flunarizine Impurity 15 (CAS 365-20-8) is a high-purity analytical reference standard with the molecular formula C13H10BrF and a molecular weight of 265.12 g/mol.

Owing to fluorine/bromine substitution, an aromatic ring system, Flunarizine Impurity 15 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 265.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
