Chemical Structure

N-Ethylhydroxylamine Hydrochloride CAS 42548-78-7 chemical structure

Description

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.

N-Ethylhydroxylamine Hydrochloride (CAS 42548-78-7), molecular formula C2H7NOHCl and molecular weight 97.54 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-Ethylhydroxylamine Hydrochloride (C2H7NOHCl) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
