(2R,3R,4S,5R,6R)-2-(Acetoxymethyl)-6-(((2S,3S,4R,5R)-3,4-diacetoxy-2,5-bis(acetoxymethyl)tetrahydrofuran-2-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate (cas: 126-14-7) belongs to tetrahydrofuran derivatives. Tetrahydrofuran and dihydrofuran form the basic structural unit of many naturally occurring scaffolds like gambieric acid A and ciguatoxin, goniocin, and some biologically active molecules. Commercial tetrahydrofuran contains substantial water that must be removed for sensitive operations, e.g. those involving organometallic compounds. Although tetrahydrofuran is traditionally dried by distillation from an aggressive desiccant, molecular sieves are superior.Product Details of 126-14-7

Topochemical activation of pulp fibres was written by Iamazaki, Eduardo T.;Orblin, Elina;Fardim, Pedro. And the article was included in Cellulose (Dordrecht, Netherlands) in 2013.Product Details of 126-14-7 This article mentions the following:

A new concept for topochem. activation of mech. pulp fibers was investigated. The activation concept was based on attachment of precursors of peracids onto the surface of the fibers prior to hydrogen peroxide bleaching. The activators used in this work were: tetraacetylethylenediamine (water soluble), lactose octaacetate (LOA, colloidal particles, and low water solubility) and sucrose octaacetate (partially soluble in water). LOA showed promising results for application in the surface activation concept due to attachment of colloidal particles on the outmost surface of the fibers, simultaneously contributing to a brightness increase. Surface coverage by lignin on fibers had decreased after the bleaching process with activators, which was detected by XPS and time-of-flight secondary ion mass spectrometry. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5R,6R)-2-(Acetoxymethyl)-6-(((2S,3S,4R,5R)-3,4-diacetoxy-2,5-bis(acetoxymethyl)tetrahydrofuran-2-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate (cas: 126-14-7Product Details of 126-14-7).
