In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Synthesis and Plant Growth Stimulating Action of 2-Amino-6-methylpyrimidine-4(3H)-thione Derivatives, published in 2020-03-31, which mentions a compound: 6307-44-4, Name is 2-Amino-6-methylpyrimidine-4-thiol, Molecular C5H7N3S, Name: 2-Amino-6-methylpyrimidine-4-thiol.
A series of new pyrimidine derivatives, e.g., I including those containing an azole or azine heterocycle linked through a sulfur atom or a thiomethylene group, was synthesized based on 2-amino-6-methylpyrimidine-4(3H)-thione. The synthesized compounds exhibited a pronounced stimulating effect on plants growth in the range of 43-96% compared to heteroauxin.
After consulting a lot of data, we found that this compound(6307-44-4)Name: 2-Amino-6-methylpyrimidine-4-thiol can be used in many types of reactions. And in most cases, this compound has more advantages.
