What is 4-Chloro-2 6-diaminopyrimidine?
4-Chloro-2 6-diaminopyrimidine, also known as 2,4-Diamino-6-chloropyrimidine or 6-Chloro-2,4-pyrimidinediamine, is a chlorinated pyrimidine compound with the CAS number 156-83-2. Its molecular formula is C₄H₅ClN₄, and its molecular weight is 144.56 g/mol. PubChem and NIST both identify it as a pyrimidine-based organohalogen compound.
From a procurement perspective, the molecule is interesting because its pyrimidine ring, chlorine substituent, and two amino groups provide useful functional positions for further chemical transformation. This makes 4-Chloro-2 6-diaminopyrimidine a useful heterocyclic building block, pharmaceutical intermediate, and specialty chemical raw material for laboratory research and synthesis projects.
The material is generally described as a white to off-white solid or crystalline powder. Reported molecular weight is 144.56 g/mol, while published data place its melting point around 199–202°C. It is only slightly soluble in water, so customers developing downstream processes should consider the solvent system and process conditions before scale-up.
Typical Application Areas
Pharmaceutical intermediate synthesis
Used as a pyrimidine intermediate and heterocyclic building block in chemical synthesis and pharmaceutical research.
