These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,56621-91-1, its application will become more common.

Adding a certain compound to certain chemical reactions, such as: 56621-91-1, 5-Amino-2-bromopyrimidine, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, 56621-91-1, blongs to pyrimidines compound. Formula: C4H4BrN3

Preparation 3 Diethyl 2-(((2-Bromopyrimidin-5-yl)amino)methylene)malonate (N.2). A mixture of 2-bromopyrimidin-5-amine (Krchnak, V.; Arnold, Z. Coll. Czech. Chem. Commun. 1975, 40, 1396-1402) (3.48 g) and diethyl ethoxymethylenemalonate (5.05 mL) is heated to 135 C. for 1 h. The mixture is allowed to cool affording a solid.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,56621-91-1, its application will become more common.
