Description

4-Pyrimidinamine, 5-Nitroso- (9Ci) is a specialized heterocyclic organic compound featuring a nitroso functional group on a pyrimidine scaffold. This compound matters as a versatile chemical intermediate and research reagent, particularly valuable for synthesizing more complex molecules in pharmaceutical and agrochemical discovery. It is needed by R&D chemists and process development scientists in the fine chemical, pharmaceutical, and life science industries for applications in medicinal chemistry and material science.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of novel drug candidates, particularly those targeting kinase inhibition or other biological pathways involving pyrimidine-based structures.
• Agrochemical Research: Used in the development and research of new herbicides, fungicides, and plant growth regulators where the nitroso-pyrimidine moiety can impart specific biological activity.
• Chemical Synthesis Reagent: Acts as a precursor for the introduction of the nitroso group or for further functionalization of the pyrimidine ring in complex organic synthesis.
• Material Science Research: Investigated for potential use in the development of organic electronic materials, ligands for metal-organic frameworks (MOFs), or photoactive compounds.
• Academic & Industrial R&D: A valuable tool for methodological studies in organic chemistry and for exploring new chemical reactions involving nitroso compounds.
