Chemical Structure

2-Amino-6-chloropyridine 1-oxide CAS 827342-99-4 chemical structure

Description

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.

2-Amino-6-chloropyridine 1-oxide (CAS 827342-99-4) is a high-purity analytical reference standard with the molecular formula C5H5ClN2O and a molecular weight of 144.56 g/mol.

Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2-Amino-6-chloropyridine 1-oxide is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
