Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,4,6-Tris(3,5-dimethylphenyl)-1,3,5,2,4,6-trioxatriborinane (CAS 34907-38-5), molecular formula C24H27B3O3 and molecular weight 395.90 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a hydroxyl group, an ether linkage, 2,4,6-Tris(3,5-dimethylphenyl)-1,3,5,2,4,6-trioxatriborinane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 395.90 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 2,4,6-Tris(3,5-dimethylphenyl)-1,3,5,2,4,6-trioxatriborinane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
