Description
2,3-O-Isopropylidene-D-erythronolactone is a protected lactone intermediate offered at a minimum purity of 95 % for organic and carbohydrate-oriented synthesis. It is registered under CAS number 25581-41-3 with the empirical formula C₇H₁₀O₄ and a molar mass of 158,15 g/mol. The isopropylidene group shields the 2,3-diol, enabling selective transformations of the D-erythronolactone framework in multi-step sequences. Medicinal and fine-chemical laboratories can use it when a compact, stereochemically defined lactone is required as a starting material or intermediate. The combination of stated purity, molecular formula, and CAS identity supports reproducible experimental design, inventory control, and regulatory documentation. This pack size balances convenience for method development with sufficient material for repeated synthetic trials in research and process chemistry settings.

Questions about 2,3-O-Isopropylidene-D-erythronolactone, min. 95 %, 10 g
What is this article?
2,3-O-Isopropylidene-D-erythronolactone, min. 95 %, 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.
