应用


  • Oxalic acid as a dual C1 surrogate for heterogeneous palladium-catalyzed tandem four-component quinazolinone synthesis.: This study explores the use of ammonium carbamate in synthesizing quinazolinones via a novel palladium-catalyzed method, highlighting its application in organic synthesis (Sheetal et al., 2024).

  • High-Capacity, Cooperative CO(2) Capture in a Diamine-Appended Metal-Organic Framework through a Combined Chemisorptive and Physisorptive Mechanism.: Ammonium carbamate is discussed in the context of enhancing CO2 capture efficiency in metal-organic frameworks, showcasing its potential in environmental applications (Zhu et al., 2024).

  • Thermal Synthesis of Carbamic Acid and Its Dimer in Interstellar Ices: A Reservoir of Interstellar Amino Acids.: The paper investigates the formation of carbamic acid from ammonium carbamate under interstellar conditions, providing insights into astrochemistry and the origins of amino acids in space (Marks et al., 2023).
