Chemical Structure
Description
The occurrence of (R)-1-(5-Bromopyridin-2-yl)ethan-1-amine hydrochloride is closely related to a nitrile group, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(R)-1-(5-Bromopyridin-2-yl)ethan-1-amine hydrochloride (CAS 953780-70-6) is a high-purity analytical reference standard with the molecular formula C7H9BrN2HCl and a molecular weight of 237.53 g/mol.
The molecular framework of (R)-1-(5-Bromopyridin-2-yl)ethan-1-amine hydrochloride (C7H9BrN2HCl) is characterized by a nitrile group, chlorine/bromine 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
