4-Hydroxypyridine (CAS 626-64-2)

Application and positioning

The 4-hydroxy tautomer of pyridine, which in most solvents is really present as 4-pyridone. A small polar building block used in kinase and antimicrobial work, supplied as a white to off-white solid. Laurand supplies it from audited Chinese producers in kilogram to multi-hundred-kilogram lots; process and regulatory documentation is coordinated case by case with the manufacturing site.
