View quality documents ↓What Is UMP disodium?
Uridine 5'-monophosphate disodium salt is a nucleotide salt supplied for professional nutrition, biochemical and formulation work. Its water, pH and moisture profile should be checked against the intended application. No. UMP disodium is the disodium salt of uridine 5-monophosphate. Specify the phosphate form and salt identity; uridine, UMP, UDP and UTP should not be substituted solely because they share the uridine name.

PGUMP-260818 · Results apply to this lot; interpret purity, assay and water on their respective bases.
- Composition candidates:
- Oral development may screen choline/DHA candidates with separate formats or emulsification for oils; enzyme work needs its own reaction system.
- Processing priorities:
- Premix low nucleotide levels; record aqueous pH, thermal exposure and hold time without describing animal-combination evidence as a human trial.
- Testing priorities:
- UMP identity, assay, sodium/hydration basis, uniformity, DHA oxidation and liquid stability.
UMP disodium formulation development: composition, processing and validation
Composition candidates, processing sequences and tests support pilot design. Confirm candidate excipients and processes using this material in the actual finished formulation.
Solid formats: carriers, loading and mixing
- Define loading by ingredient mass, salt mass or active moiety. Use m = target mass / assay as supplied only when both share the same basis; convert dried-basis assays using water where appropriate, and do not substitute HPLC area purity for mass assay. Set excipient amounts from fill mass, bulk density and uniformity trials.
- Oral development may screen choline/DHA candidates with separate formats or emulsification for oils; enzyme work needs its own reaction system.
- Record ingredient lots, actual component masses, loading bases and addition sequence, retaining blanks and single-ingredient controls for traceable changes.
Processing and formats: pilot batches through filling
- Premix low nucleotide levels; record aqueous pH, thermal exposure and hold time without describing animal-combination evidence as a human trial.
- Select blending/filling equipment for the actual format, recording size, bulk density, mixing time and fill mass; liquid or softgel routes need separate carrier, sedimentation and container/shell compatibility testing.
Validation and scale-up: tests, retained samples and packaging
- UMP identity, assay, sodium/hydration basis, uniformity, DHA oxidation and liquid stability.
- Sample upper/middle/lower positions and start/middle/end filling; compare with ingredients, process blanks and single-ingredient results, documenting deviations and corrections.
- Include actual packaging, transport and intended storage in retained-sample plans; ingredient COAs and storage conditions do not establish a new finished-product shelf life.

Animal combination studyUMP + choline + DHA phospholipid-precursor research
UMP, choline and DHA have been studied together as substrates relevant to phospholipid synthesis. For a nutraceutical concept, assess powder blend uniformity and UMP assay alongside DHA oxidation protection, choline salt choice, odor, encapsulation and shelf stability; each component needs its own identity and potency specification.

Development rationale: UMP, choline and DHA have been studied together as substrates relevant to phospholipid synthesis. For a nutraceutical concept, assess powder blend uniformity and UMP assay alongside DHA oxidation protection, choline salt choice, odor, encapsulation and shelf stability; each component needs its own identity and potency specification.
Evidence scope: The cited UMP/choline/DHA combination increased brain phospholipid measures in gerbils and included behavioral testing; it is animal evidence only. It does not establish human cognitive benefit, an optimal commercial ratio, or efficacy of this UMP grade.
Pilot checks: Handle oils and water-soluble ingredients separately; compare separate formats, dispersion or emulsification, checking sedimentation, oxidation and packaging compatibility.

Scientific Research
2. Human UMP studies measured circulating uridine and feeding responses
Two placebo-controlled human experiments administered a single oral dose of UMP and measured circulating uridine, hunger ratings and food intake. The paper discusses short-term physiological responses; it is not evidence for a chronic nutrition or clinical outcome.

3. Small detraining study of 5′-UMP
A randomized, double-blind study assigned 21 healthy men to UMP or placebo during a two-week detraining period. One upper-arm measurement differed at week one, while other measured sites did not show a significant between-group difference. The authors describe a short, exploratory study; independent replication is needed.

Is UMP disodium the same material as uridine?+
No. UMP disodium is the disodium salt of uridine 5-monophosphate. Specify the phosphate form and salt identity; uridine, UMP, UDP and UTP should not be substituted solely because they share the uridine name.
What are the identity and specification of UMP disodium powder?+
Uridine 5-monophosphate disodium (UMP disodium) powder, CAS 3387-36-8, has an HPLC assay specification of ≥98.0%. Specify both the 5-monophosphate and disodium identities, and review the matching batch COA for identity and assay.
How should UMP disodium quantities be calculated for biochemical systems?+
Calculate UMP disodium concentrations using the specified salt, hydration form, molecular weight and lot assay basis. Uridine, UMP, UDP and UTP are distinct materials and should not be substituted by similar names or equal powder mass.
