Chemical Structure
Description
1-(3,5-Dichlorophenyl)cyclopentanamine (CAS 1176739-99-3) is a high-purity analytical reference standard with the molecular formula C11H13Cl2N and a molecular weight of 230.13 g/mol.
The molecular framework of 1-(3,5-Dichlorophenyl)cyclopentanamine (C11H13Cl2N) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, 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. 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.
