The systematic study of pyrimidines began in 1884 with Pinner, who synthesized derivatives by condensing ethyl acetoacetate with amidines. Pinner first proposed the name “pyrimidin” in 1885. 4595-59-9, formula is C4H3BrN2, Name is 5-Bromopyrimidine. The parent compound was first prepared by Gabriel and Colman in 1900, by conversion of barbituric acid to 2,4,6-trichloropyrimidine followed by reduction using zinc dust in hot water. HPLC of Formula: 4595-59-9.
Dewan, Anindita;Sarmah, Manashi;Bharali, Pankaj;Thakur, Ashim J.;Boruah, Purna K.;Das, Manash R.;Bora, Utpal research published 《 Pd Nanoparticles-Loaded Honeycomb-Structured Bio-nanocellulose as a Heterogeneous Catalyst for Heteroaryl Cross-Coupling Reaction》, the research content is summarized as follows. Distorted honeycomb-like hollow cage-structured bio-nanocellulose (with 1-16.7μm diameters) is derived from cellulosic waste of pomegranate peel using a simple microwave technique in water under neutral conditions without using external chems. in a very short period of time. Pd nanoparticles are loaded onto the bio-nanocellulose surface by simple stirring at room temperature (25°C) and characterized by X-ray diffraction, SEM, transmission electron microscopy, Fourier-transform IR spectroscopy, Brunauer-Emmett-Teller surface area analyses, and so on. The newly developed nanocomposite material has been utilized as an efficient heterogeneous catalyst for the synthesis of potential bioactive biaryl/heterobiaryl and alkynyl/heteroalkynyl derivatives up to 98% yield via the Suzuki-Miyaura and Sonogashira cross-coupling reactions. The catalyst is reusable up to five catalytic cycles without significant loss of its catalytic activity. Waste pomegranate peel-derived honeycomb-like bio-nanocellulose serves as a heterogeneous surface for Pd nanoparticles which catalyze a variety of cross-coupling reactions.
4595-59-9, 5-Bromopyrimidine is a reactive intermediate that is used in the synthesis of 4-methoxyphenylboronic acid. 5-Bromopyrimidine has been shown to be nucleophilic, reacting with β-amino acids under basic conditions to form the corresponding 2-bromo amide. It also undergoes cross-coupling reactions with halides and can be used as a building block for other organic compounds. 5-Bromopyrimidine has optical properties that are characteristic of aromatic molecules, including strong absorption bands in the ultraviolet region and visible light region.
5-Bromopyrimidine undergoes direct metallation with lithuium diisopropylamide to yield 4-lithio-5-bromopyrimidine., HPLC of Formula: 4595-59-9
