Uridine 5′-monophosphomorpholidate 4-morpholine-N,N′-dicyclohexylcarboxamidine salt is an activated derivative of uridine 5'-monophosphate (UMP), primarily used in chemical synthesis of oligonucleotides and nucleotide analogs. It serves as a key intermediate in the phosphomorpholidate method for forming phosphodiester or pyrophosphate bonds, enabling the assembly of RNA and DNA oligomers. This compound is essential in biochemical research for studying nucleic acid synthesis, preparing modified nucleotides, and developing oligonucleotide-based therapeutics. It is also utilized in the synthesis of sugar nucleotides, such as UDP-sugars, and in molecular biology applications including the creation of probes for PCR, sequencing, and gene expression analysis.
