Product Description:
Can be used for Tablets, capsules, film-coated, pills, suppositories, etc.
In the production process, PEG can improve the plasticity and release the drug tablets. High molecular weight PEG (PEG4000 and PEG6000) is useful adhesives to manufacture tablets.
PEG allows the surface of tablets shiny and smooth, so it not easy to damage.
1.Chemical uses
PEG is the basis of a number of laxatives. Whole bowel irrigation with polyethylene glycol and added electrolytes is used for bowel preparation before surgery or colonoscopy.PEG is also used as an excipient in many pharmaceutical products.When attached to various protein medications, polyethylene glycol allows a slowed clearance of the carried protein from blood.
2.Medical uses
PEG is often used (as an internal calibration compound) in mass spectrometry experiments, with its characteristic fragmentation pattern allowing accurate and reproducible tuning.
PEG derivatives, such as narrow range ethoxylates, are used as surfactants.
PEG has been used as the hydrophilic block of amphiphilic block copolymers used to create some polymersomes.
3.Biological uses
PEG is commonly used as a precipitant for plasmid DNA isolation and protein crystallization. X-ray diffraction of protein crystals can reveal the atomic structure of the proteins.
PEG is used to fuse two different types of cells, most often B-cells and myelomas in order to create hybridomas.
4.Commercial uses
PEG is the basis of many skin creams (as cetomacrogol) and personal lubricants (frequently combined with glycerin).
PEG is used in a number of toothpastes as a dispersant. In this application, it binds water and helps keep xanthan gum uniformly distributed throughout the toothpaste.

FAQ
Application Area:
Uridine 5-Mophosphate Disodium are produced through the hydrolytic reaction from Ribonucleic acid(RNA) as raw material by enzymatic catalysis to form four kinds of nucleotides 5- 'AMP (adenosine-5'-monophosphate), 5'-GMP•2Na(guanosine-5'-monophosphate, disodium salt), 5'-CMP(cytidine-5'-monophosphate)-, 5'-UMP•2Na (uridine- 5'-monophosphate,Disodium salt) .By the chromatographic isolation, four kinds of separated 5'-nucleotide products with high purity can be obtained. These products can be widely applied in medicine, reagent, fine chemical industry, and additive of food fields etc.
