10-Deacetylbaccatin III; (2aR,4S,4aS,6R,9S,11S,12S,12aR,12bS)-12b-acetoxy-4,6,9,11-tetrahydroxy-4a,8,13,13-tetramethyl-5-oxo-2a,3,4,4a,5,6,9,10,11,12,12a,12b-dodecahydro-1H-7,11-methanocyclodeca[3,4]benzo[1,2-b]oxet-12-yl benzoate; CAS No.: 32981-86-5; ChemShuttle provides complex taxane derivatives as pharma building blocks for oncology research. The dodecahydro-benzooxetene core and multiple hydroxyl groups enable microtubule stabilization. Our semi-synthetic process from 10-deacetylbaccatin III achieves precise acetylation patterns. The product supports development of next-generation taxoids with improved solubility and reduced neurotoxicity.
