Description
As a certified reference material (CRM), 4,4,5,5-tetramethyl-2-[10-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)anthracen-9-yl]-1,3,2-dioxaborolane 863992-56-7 AS-2438 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.
CATO supplies 4,4,5,5-tetramethyl-2-[10-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)anthracen-9-yl]-1,3,2-dioxaborolane 863992-56-7 AS-2438 (CAS 863992-56-7), a certified reference material (molecular formula C26H46B2O4, MW 444.26 g/mol) for analytical method development and quality control.
Owing to a steroid core, a hydroxyl group, an ether linkage, 4,4,5,5-tetramethyl-2-[10-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)anthracen-9-yl]-1,3,2-dioxaborolane 863992-56-7 AS-2438 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 444.26 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
