Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 265.74 g/mol gives 4-(4-ethoxyphenoxy)aniline hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-(4-ethoxyphenoxy)aniline hydrochloride (CAS 6889-04-9), molecular formula C14H15NO2HCl and molecular weight 265.74 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(4-ethoxyphenoxy)aniline hydrochloride (C14H15NO2HCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
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.
