Chemical Structure
Description
Owing to a steroid core, a hydroxyl group, an ether linkage, 2,7-Bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)triphenylene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 480.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
2,7-Bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)triphenylene (CAS 929103-40-2), molecular formula C30H34B2O4 and molecular weight 480.21 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
