CAS 55717-45-8: 2-Bromo-5-hydroxypyridine

It is used as an active pharmaceutical intermediate and in the coupling reactions with halo aromatic amines and alcohols for a practical synthetic route to 2-substituted amino phenyl and hydroxyphenyl pyridines. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

2-Bromo-5-hydroxypyridine is an aromatic compound that is used in the synthesis of a variety of pharmaceuticals and other organic compounds. It can be synthesized by the Suzuki coupling reaction from 2-bromobenzaldehyde and 5-aminopyridine. 2-Bromo-5-hydroxypyridine has been shown to be a hepatotoxin in humans, with possible carcinogenic activity. It also has cholinergic properties, as well as being able to cause fluorescence when exposed to halogens. The carbon next to the hydroxyl group is a stereocenter, so there are two different configurations for this molecule. The configuration shown above (R) is the more stable form of this molecule due to its electron withdrawing power on the neighboring oxygen atom.
