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.

Medicinal chemistry

The pyrimidine scaffold is widely used in medicinal chemistry programs, making this compound relevant to small-molecule research and intermediate development.

Superior 4-Chloro-2 6-diaminopyrimidine Series | Reliable Quality & Sufficient Supply

For procurement teams, the main question is usually not simply “Can you supply CAS 156-83-2?” It is whether the supplier can provide consistent quality, repeatable batches, reasonable lead times and enough material when the project moves from laboratory testing to larger-scale production.

Zhishangbio positions 4-Chloro-2 6-diaminopyrimidine CAS 156-83-2 as a bulk-supply chemical rather than a small-pack laboratory-only product. Public product information lists 99% purity, a minimum order quantity of 1 kg, and a stated supply capacity of 30 metric tons per month, with 25 kg drums available.

Our production and QC approach focuses on controlling the key points that matter to industrial buyers: raw-material selection, reaction control, purification, drying and batch testing. Before shipment, customers can request quality documentation such as a COA and relevant technical documentation according to the order requirements.

For customers comparing 4-Chloro-2 6-diaminopyrimidine suppliers, this supply model is designed to support different purchasing stages—from an initial 1 kg sample or development order to repeated kilogram and larger-volume procurement.

4-Chloro-2 6-diaminopyrimidine Supply Plan & Delivery Schedule

A reliable 4-Chloro-2 6-diaminopyrimidine supplier should be able to explain what happens after a purchase inquiry. Our standard B2B workflow is designed to keep the process clear from specification review through shipment.
