Compared with other compounds in its class, the molecular weight of 413.92 g/mol gives 1,3,5-Tris(5,5-dimethyl-1,3,2-dioxaborinan-2-yl)benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,3,5-Tris(5,5-dimethyl-1,3,2-dioxaborinan-2-yl)benzene (CAS 916330-18-2), molecular formula C21H33B3O6 and molecular weight 413.92 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,3,5-Tris(5,5-dimethyl-1,3,2-dioxaborinan-2-yl)benzene (C21H33B3O6) is characterized by a steroid core, a hydroxyl group, an ether linkage. 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 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 1,3,5-Tris(5,5-dimethyl-1,3,2-dioxaborinan-2-yl)benzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
