Description
D(+)-Trehalose dihydrate is a high-purity disaccharide hydrate supplied at min. 98 % under the CELLPURE® grade, with CAS number 6138-23-4 and empirical formula C₁₂H₂₂O₁₁ · 2 H₂O. Its molar mass is 378,24 g/mol, supporting precise stoichiometric work in biochemical and carbohydrate research. This non-reducing sugar is widely used as a stabilizer for proteins, enzymes and membranes, in lyophilization protocols, and as a reference material in carbohydrate analysis. Offered from manufacturer Carl ROTH, the product fits workflows in cell culture support, cryoprotection research and disaccharide chemistry. Clear identity data including EG nr. 202-739-6 facilitate documentation and inventory control. Suitable for laboratories requiring a defined trehalose dihydrate grade for analytical and preparative applications without unnecessary additives or unspecified purity claims.

Questions about D(+)-Trehalose dihydrate, min. 98 %, CELLPURE®, 10 g, plastic
What is this article?
D(+)-Trehalose dihydrate, min. 98 %, CELLPURE®, 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.
Which category should I open next?
The category is Biochemicals & reagents. The sub-category is Carbohydrates & sugars. The catalogue is Life Science & Microbiology.
