Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 2,4,6-Tris(3-fluoro-4-methoxyphenyl)-1,3,5,2,4,6-trioxatriborinane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 169.95 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
2,4,6-Tris(3-fluoro-4-methoxyphenyl)-1,3,5,2,4,6-trioxatriborinane (CAS 149506-26-3), molecular formula C7H8BFO3 and molecular weight 169.95 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.
