Description
A wide range of MagniSolv deuterated solvents with extremely low residual water, excellent chemical purity, and the highest isotopic enrichment available can satisfy the most demanding requirements of researchers. Depending on application and sensitivity of the NMR spectrometer our offer solvents with deuteration degrees between 98% and 99.96%. In case of all the water soluble deuterated standard products, water content is specified according to both Karl Fischer and NMR.Methanol-D4 deuteration degree min. 99.8 % for NMR spectroscopy MagniSolv. CAS 811-98-3, chemical formula CDOD, molar mass 36.07 g/mol.
Application
4'-Demethylepipodophyllotoxin serves as a key synthetic intermediate in the development of topoisomerase II inhibitors, featuring a phenolic hydroxyl group at the 4' position that enables derivatization for structure-activity studies. Its stable core structure facilitates functionalization under standard conditions, offering reliable access to epipodophyllotoxin analogs with enhanced pharmacological profiles.
