Chemical Structure
Description
4-(2-(4-Nitrophenoxy)ethoxy)aniline hydrochloride (CAS 19157-80-3) is a high-purity analytical reference standard with the molecular formula C14H14N2O4HCl and a molecular weight of 310.73 g/mol.
Structurally, 4-(2-(4-Nitrophenoxy)ethoxy)aniline hydrochloride (C14H14N2O4HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 310.73 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 4-(2-(4-Nitrophenoxy)ethoxy)aniline hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
