Chemical Structure
Description
The occurrence of 2-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)thiophene-3-carbonitrile is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)thiophene-3-carbonitrile (CAS 463336-26-7) is a high-purity analytical reference standard with the molecular formula C11H14BNO2S and a molecular weight of 235.11 g/mol.
2-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)thiophene-3-carbonitrile (C11H14BNO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 2-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)thiophene-3-carbonitrile 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.
