2-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-indol-4-yl acetate (CAS 1072811-58-5), molecular formula C16H20BNO4 and molecular weight 301.15 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-indol-4-yl acetate (C16H20BNO4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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.
