Darifenacin Impurity 8 CAS 87776-69-9

Description

Compared with other compounds in its class, the molecular weight of 164.20 g/mol gives Darifenacin Impurity 8 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Darifenacin Impurity 8 (CAS 87776-69-9), a certified reference material (molecular formula C10H12O2, MW 164.20 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Darifenacin Impurity 8 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 164.20 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.

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

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.
