This compound, [2-(iso-Propoxy)-4-methyl-d10]-pyrimidine-5-boronic acid, is a specialty chemical intermediate primarily utilized in organic synthesis, particularly in cross-coupling reactions such as the Suzuki-Miyaura reaction. The boronic acid functional group at the 5-position of the pyrimidine ring enables the formation of carbon-carbon bonds with aryl or vinyl halides, making it valuable for constructing complex organic molecules in pharmaceuticals and agrochemicals. The deuterated methyl group (d10) at the 4-position provides isotopic labeling, enhancing specificity and stability in reactions while allowing precise tracking in metabolic studies without significantly altering reactivity. It is especially relevant for developing deuterated analogs in research and drug discovery to investigate biological pathways.
