2-Amino-3-hydroxypyridine CAS 16867-03-1

Description

Compared with other compounds in its class, the molecular weight of 110.11 g/mol gives 2-Amino-3-hydroxypyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Amino-3-hydroxypyridine (CAS 16867-03-1), molecular formula C5H6N2O and molecular weight 110.11 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, 2-Amino-3-hydroxypyridine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 110.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
