Chemical Structure
Description
As a certified reference material (CRM), 4,4,5,5-Tetramethyl-2-(1-methylcyclopropyl)-1,3,2-dioxaborolane 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.
4,4,5,5-Tetramethyl-2-(1-methylcyclopropyl)-1,3,2-dioxaborolane (CAS 126689-04-1), molecular formula C10H19BO2 and molecular weight 182.07 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 4,4,5,5-Tetramethyl-2-(1-methylcyclopropyl)-1,3,2-dioxaborolane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 182.07 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.
