2,5,6-Triamino-4-pyrimidinol sulfate
2,5,6-Triamino-4-pyrimidinol sulfate (CAS: 35011-47-3), also known as 2,4,5-triamino-6-hydroxypyrimidine sulfate, is a polyfunctional pyrimidine derivative bearing multiple amino groups and a hydroxyl functionality on a nitrogen-rich heteroaromatic ring. This white crystalline solid is a strategic intermediate in the synthesis of folic acid, vitamin B9, and a wide range of pteridine-based compounds, where the pyrimidine core serves as the foundational ring structure. Its rich nitrogen chemistry enables selective diazotization, cyclocondensation, and coupling reactions under controlled conditions. The compound is also employed in the production of certain pharmaceuticals, agrochemicals, and specialty dyes. Manufactured under strict quality controls to ensure high assay and low impurity levels, it supports reproducible multi-step syntheses. Proper storage in cool, dry conditions preserves its stability and reactivity for downstream processing.
– Folic Acid Production: Serves as a key pyrimidine intermediate in the industrial synthesis of folic acid and related folate derivatives for food fortification and nutritional supplements.
– Pharmaceutical Synthesis: Used in the construction of dihydrofolate reductase inhibitors and other pteridine-based active pharmaceutical ingredients.
– Agrochemical Manufacturing: Employed as a building block for nitrogen-rich heterocyclic compounds used in crop protection chemicals.
– Specialty Dye Chemistry: Applied in the synthesis of azo and heterocyclic dyes where the polyfunctional pyrimidine ring provides chromophore attachment points.
