Description
2,3-O-Isopropylidene-D-ribonic acid-1,4-lactone is a protected sugar lactone for laboratory and biochemical chemistry. It carries CAS number 30725-00-9, the empirical formula C₈H₁₂O₅, and a molar mass of 188,18 g/mol. The 2,3-O-isopropylidene protection together with the 1,4-lactone arrangement provides a defined ribose-derived intermediate for carbohydrate synthesis and related organic transformations. The product is From manufacturer Carl ROTH, this reagent supports research programmes that rely on characterised protected sugar building blocks. Clear CAS and formula assignment aid inventory tracking, batch documentation, and stoichiometric planning. balances convenient handling with sufficient material for extended synthetic sequences. Laboratories engaged in chiral-pool chemistry, protected-sugar manipulation, or related preparative routes can draw on this lactone as a specified starting material. Stated molar mass enables accurate charge calculations throughout experimental workflows without ambiguity about molecular composition.

Questions about 2,3-O-Isopropylidene-D-ribonic acid-1,4-, lactone, 10 g
What is this article?
2,3-O-Isopropylidene-D-ribonic acid-1,4-, lactone, 10 g is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Organic building blocks & synthesis reagents, inside Organic chemicals & synthesis reagents, in Lab chemicals.
A building block is an organic molecule bought to become part of a larger one. The structure, the CAS number and the purity decide it. A 95 percent reagent and a 99.9 percent reagent of the same name leave different impurities in the product. The functional groups are the reason it was chosen.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
