4,5-Pyrimidinediamine(CAS: 13754-19-3)

4,5-Pyrimidinediamine (CAS: 13754-19-3) is a crystalline solid with a molecular weight of approximately 117.11 g/mol. It has a maximum solubility in water at 25°C of 0.08g/100ml. It is moderately reactive, particularly with acids and bases, and can undergo nitration and sulfonation. The compound is basic in nature and can form complexes with various metal ions.

4,5-Pyrimidinediamine can be synthesized via the condensation of 4,5-pyrimidine dicarboxaldehyde and hydrazine. Another method involves the reduction of 4,5-pyridinedicarboxylic acid hydrazide. Commonly, this synthesis requires mild to moderate conditions and can achieve good yields with appropriate choice of solvents and reagents.

4,5-Pyrimidinediamine is used in the pharmaceutical industry for the synthesis of certain drugs, in the polymer industry for modifying properties of polymers, and in the sensor industry for the development of gas sensors. It also finds applications in the semiconductor industry as a dopant and in the production of certain dyes.

When handling 4,5-Pyrimidinediamine (CAS: 13754-19-3), it is essential to wear appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. Work should be conducted in a fume hood to minimize inhalation. Spills should be cleaned up using absorbent materials and disposed of according to local regulations. Always consult the Safety Data Sheet (SDS) for detailed handling instructions.
