4-Hydroxy-6-(trifluoromethyl)pyrimidine丨CAS 1546-78-7

4-Hydroxy-6-(trifluoromethyl)pyrimidine (CAS 1546-78-7) is a heterocyclic compound widely used as an intermediate in pharmaceutical, agrochemical, and fine chemical synthesis. Its pyrimidine core and trifluoromethyl substitution make it a versatile building block for the development of bioactive molecules, including antiviral, anticancer, and antibacterial agents. It is commonly employed in medicinal chemistry to construct nucleoside analogs, kinase inhibitors, and enzyme modulators, where the trifluoromethyl group enhances lipophilicity and metabolic stability. Additionally, it is used in the synthesis of functionalized heterocycles, fluorinated compounds, and specialty chemicals, supporting the creation of compound libraries for structure–activity relationship (SAR) studies.

The benefits of 4-Hydroxy-6-(trifluoromethyl)pyrimidine arise from its chemically robust structure and reactive functional groups. The hydroxy group enables derivatization through alkylation, acylation, and condensation reactions, while the trifluoromethyl group improves chemical stability, electron-withdrawing capacity, and bioavailability in target molecules. Its solubility in organic solvents and compatibility with standard synthetic conditions make it suitable for laboratory and industrial use. The presence of the trifluoromethyl group also enhances the pharmacokinetic properties of derivatives, improving metabolic resistance, membrane permeability, and binding affinity in drug design.
