CATO supplies 7,13-Bis-O-(triethylsilyl)-10-deacetyl-10-oxo Baccatin III (CAS 651293-82-2), a certified reference material (molecular formula C41H62O10Si2, MW 771.10 g/mol) for analytical method development and quality control.
The molecular framework of 7,13-Bis-O-(triethylsilyl)-10-deacetyl-10-oxo Baccatin III (C41H62O10Si2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
