Cas no 1935996-83-0 (1H-Pyrazol-5-ol, 4-bromo-1-methyl-)
4-Bromo-1-methyl-1H-pyrazol-5-ol is a brominated pyrazole derivative with a hydroxyl group at the 5-position and a methyl substituent at the 1-position. This compound serves as a versatile intermediate in organic synthesis, particularly in the preparation of pharmaceuticals, agrochemicals, and functional materials. Its bromine moiety enhances reactivity for further functionalization, enabling selective cross-coupling or substitution reactions. The methyl group improves stability and influences the electronic properties of the pyrazole ring. The hydroxyl group offers additional modification potential, such as etherification or complexation. This compound is valued for its well-defined structure, consistent purity, and utility in constructing heterocyclic frameworks for research and industrial applications.
