Chemical Structure

rel-(1R,2R)-2-Fluorocyclopentan-1-amine hydrochloride CAS 2125943-82-8 chemical structure

Description

rel-(1R,2R)-2-Fluorocyclopentan-1-amine hydrochloride (CAS 2125943-82-8), molecular formula C5H10FNHCl and molecular weight 139.60 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of rel-(1R,2R)-2-Fluorocyclopentan-1-amine hydrochloride (C5H10FNHCl) is characterized by fluorine/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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
