Cipepofol Impurity 3 CAS 1637741-59-3

Description

Compared with other compounds in its class, the molecular weight of 204.31 g/mol gives Cipepofol Impurity 3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Cipepofol Impurity 3 (CAS 1637741-59-3) is a certified pharmaceutical impurity reference standard with the molecular formula C14H20O and a molecular weight of 204.31 g/mol.

Owing to a hydroxyl group, an ether linkage, an aromatic ring system, Cipepofol Impurity 3 is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 204.31 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.

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.

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.
