Description
D-Ribose-5-phosphate disodium salt is a biochemistry-grade reagent supplied at min. 85 % purity, with CAS number 18265-46-8 and empirical formula C₅H₉Na₂O₈P. The disodium salt has a molar mass of 274,08 g/mol and is used in work on carbohydrate metabolism, pentose phosphate pathway intermediates, and enzymatic assays that involve phosphorylated sugars. The product is available from manufacturer Carl ROTH for research and analytical biochemistry laboratories and is identified by EG number 242-140-7. D-Ribose-5-phosphate participates in nucleotide precursor routes and is relevant to metabolic flux studies, enzyme kinetics, and reconstituted pathway systems. The disodium form supports handling and aqueous buffer use in many standard laboratory protocols. Laboratories choose this intermediate when preparing substrate stocks, calibration materials, or pathway reconstitution mixtures that require a defined ribose phosphate salt at biochemistry-oriented purity in a compact glass pack.

Questions about D-Ribose-5-phosphate disodium salt, min. 85 %, for biochemistry, 250 mg, glass
What is this article?
D-Ribose-5-phosphate disodium salt, min. 85 %, for biochemistry, 250 mg, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Carbohydrates & sugars, inside Biochemicals & reagents, in Life Science & Microbiology.
A carbohydrate reagent is a sugar or a derivative, specified by identity, anomer where it matters, and purity. Hydrate and anhydrous forms change the mass. A culture-grade sugar and an analytical standard of the same name are different bottles.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
