2-Hydroxy-5-methylpyridine

2-Hydroxy-5-methylpyridine (also 5-methyl-2-pyridinol) is a valuable intermediate in organic synthesis, mainly used in the pharmaceutical and agrochemical industries to build complex, biologically active molecules like antifibrotic drugs (e.g., Pirfenidone), sedatives, and potential new therapeutic agents, serving as a key building block due to its reactive hydroxyl group.
