Chemical Structure
Description
The occurrence of 7-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)benzo[d]isothiazole is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
7-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)benzo[d]isothiazole (CAS 1326713-92-1), molecular formula C13H16BNO2S and molecular weight 261.15 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 7-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)benzo[d]isothiazole (C13H16BNO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
