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 Crystal engineering with pyrazolyl-thiazole derivatives: structure-directing role of π-stacking and σ-hole interactions, published in 2021, which mentions a compound: 70-23-5, Name is Ethyl 3-bromo-2-oxopropanoate, Molecular C5H7BrO3, Product Details of 70-23-5.
The synthesis and X-ray characterization of 1-(2-(3-(4-bromophenyl)-5-(4-methoxyphenyl)-4,5-dihydro-1H-pyrazol-1-yl)-4-methylthiazol-5-yl)ethanone (7), Et 2-(5-(4-bromophenyl)-3-(4-chlorophenyl)-4,5-dihydropyrazol-1-yl)thiazole-4-carboxylate (8) and 2-(5-(4-chlorophenyl)-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl)-N’-(2-hydroxy-3-methoxybenzylidene)thiazole-4-carbohydrazide (10) are described in this manuscript. The structure-directing role of a variety of noncovalent interactions has been analyzed energetically using DFT calculations and Hirshfeld surface anal. Moreover, the existence and importance of halogen and chalcogen bonding interactions have been analyzed by using the quantum theory of atoms in mols. and the noncovalent interaction index (NCIplot).
In addition to the literature in the link below, there is a lot of literature about this compound(Ethyl 3-bromo-2-oxopropanoate)Product Details of 70-23-5, illustrating the importance and wide applicability of this compound(70-23-5).
