Guanosine monophosphate

Guanosine monophosphate (CAS 85-32-5), also known as 5'-guanylic acid and guanosine-5'-monophosphate, is a purine nucleotide used commercially as a flavor enhancer and acidulant in food manufacturing.

Where is Guanosine monophosphate used?

• Processed food: combined with inosine monophosphate and monosodium glutamate to intensify umami in soups, seasonings, snack coatings and instant noodles
• Flavor houses: incorporated into proprietary savory blends where precise nucleotide ratios determine the final taste profile
• Pharmaceutical and biotechnology: biochemical reference material and building block in nucleotide synthesis workflows
• Research and diagnostic suppliers source it for cell biology assays requiring enzymatic studies with defined nucleotide substrates.

Commercial specifications

• Bulk quantities standard for food ingredient procurement; smaller pack sizes for pharmaceutical and laboratory use
