Chemical Structure
Description
1-(5-Bromopyridin-2-yl)ethan-1-amine dihydrochloride (CAS 1956322-54-5), molecular formula C7H9BrN2HCl and molecular weight 237.53 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-(5-Bromopyridin-2-yl)ethan-1-amine dihydrochloride (C7H9BrN2HCl) contains a nitrile group, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 237.53 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
