Chemical Structure
Description
((Benzene-1,3,5-triyltris(ethyne-2,1-diyl))tris(benzene-4,1-diyl))triboronic acid (C30H21B3O6) contains a steroid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
((Benzene-1,3,5-triyltris(ethyne-2,1-diyl))tris(benzene-4,1-diyl))triboronic acid (CAS 1019209-39-2) is a high-purity analytical reference standard with the molecular formula C30H21B3O6 and a molecular weight of 509.92 g/mol.
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.
