Compared with other compounds in its class, the molecular weight of 150.22 g/mol gives Butoxybenzene Impurity 15 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Butoxybenzene Impurity 15 (CAS 1126-75-6), a pharmacopoeial impurity reference standard (molecular formula C10H14O, MW 150.22 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Butoxybenzene Impurity 15 (C10H14O) is characterized by a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
