5-Bromo-4-chloro-3-iodopyridin-2-amine CAS 1228666-03-2

Description

The occurrence of 5-Bromo-4-chloro-3-iodopyridin-2-amine is closely related to chlorine/bromine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-Bromo-4-chloro-3-iodopyridin-2-amine (CAS 1228666-03-2), a certified reference material (molecular formula C5H9BrClIN2, MW 339.40 g/mol) for analytical method development and quality control.

Based on its molecular formula C5H9BrClIN2, 5-Bromo-4-chloro-3-iodopyridin-2-amine contains chlorine/bromine/iodine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 339.40 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
