Description
D(−)-Ribose is a monosaccharide for biochemistry supplied at minimum 98 % purity, with CAS number 50-69-1, EG nr. 200-059-4, and empirical formula C₅H₁₀O₅. The sugar has a molar mass of 150,13 g/mol, a density of 1,59 g/cm³, and a boiling point above 150 °C, supporting its use as a defined carbohydrate building block in analytical and preparative work. This is intended for laboratories handling carbohydrates, nucleotide-related chemistry, and general biochemical research where a high-purity aldopentose is required. Physical constants and assay data allow straightforward integration into method documentation and material specifications. Offered by manufacturer Carl ROTH within the monosaccharides range, D(−)-Ribose suits stock solutions, reference preparations, and synthetic or metabolic studies that depend on consistent sugar identity. The compact unit quantity supports both single experiments and small-series workflows without excess inventory.
This article is part of Carbohydrates & sugars, in Biochemicals & reagents.

Questions about D(-)-Ribose, min. 98 %, for biochemistry, 10 g, plastic
What is this article?
D(-)-Ribose, min. 98 %, for biochemistry, 10 g, plastic 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.
