Description
L(+)-Rhamnose monohydrate is a biochemical-grade monosaccharide with a minimum purity of 98 %, intended for biochemistry applications. Identified by CAS number 10030-85-0 and empirical formula C₆H₁₂O₅ · H₂O, it has a molar mass of 182,17 g/mol and a density of 1,397 g/cm³. Its boiling point lies between 123,3 and 139,6 °C. This deoxy sugar is widely used in carbohydrate chemistry, glycosylation studies, microbial metabolism work, and other laboratory protocols that require a defined L-rhamnose source. Clear labelling of CAS and EG identifiers aids inventory control and documentation in regulated research environments. The monohydrate form offers convenient handling for weighing and solution preparation in routine biochemical workflows across academic, industrial, and diagnostic laboratories.
This article is part of Carbohydrates & sugars, in Biochemicals & reagents.

Questions about L(+)-Rhamnose monohydrate, min. 98 %, for biochemistry, 5 g, glass
What is this article?
L(+)-Rhamnose monohydrate, min. 98 %, for biochemistry, 5 g, 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.
