N-(3-Aminopropyl)-5-chloro-1-naphthalenesulfonamide hydrochloride CAS 78957-86-5

Description

Compared with other compounds in its class, the molecular weight of 335.24 g/mol gives N-(3-Aminopropyl)-5-chloro-1-naphthalenesulfonamide hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N-(3-Aminopropyl)-5-chloro-1-naphthalenesulfonamide hydrochloride (CAS 78957-86-5), molecular formula C13H15ClN2O2SHCl and molecular weight 335.24 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C13H15ClN2O2SHCl, N-(3-Aminopropyl)-5-chloro-1-naphthalenesulfonamide hydrochloride contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 335.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

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.
