Description

Ump Dipotassium Salt CAS NO 35477-81-7 is a high-purity biochemical reagent, specifically the dipotassium salt of uridine 5'-monophosphate. This compound is essential as a key nucleotide building block and intermediate in various biosynthetic and research pathways. It is primarily required by manufacturers in the pharmaceutical, biotechnology, and life science research sectors for applications in oligonucleotide synthesis, cell culture media formulation, and enzymatic studies.

Application

• Oligonucleotide and DNA/RNA Synthesis: Serves as a critical raw material (phosphoramidite precursor) for the solid-phase synthesis of oligonucleotides.
• Cell Culture and Media Supplements: Used as a nucleotide component in specialized cell culture media to support the growth of fastidious cell lines.
• Enzymatic and Biochemical Research: Acts as a substrate or co-factor in enzymatic assays and studies of kinases, polymerases, and other nucleotide-dependent enzymes.
• Diagnostic Reagent Manufacturing: Employed in the formulation of diagnostic kits and reagents, particularly those involving molecular biology techniques.
• Pharmaceutical Intermediates: Functions as a key intermediate in the synthesis of more complex nucleoside-based antiviral or anticancer prodrugs.
• Biocatalyst and Enzyme Cofactor: Utilized in biocatalytic processes where nucleotide cofactors are required to drive enzymatic reactions.
