Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 4,4,5,5-Tetramethyl-2-((1R,2R)-2-(5-methylthiophen-2-yl)cyclopropyl)-1,3,2-dioxaborolane (CAS 2170979-94-7), a certified reference material (molecular formula C14H21BO2S, MW 264.19 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 4,4,5,5-Tetramethyl-2-((1R,2R)-2-(5-methylthiophen-2-yl)cyclopropyl)-1,3,2-dioxaborolane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 264.19 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).
As a certified reference material (CRM), 4,4,5,5-Tetramethyl-2-((1R,2R)-2-(5-methylthiophen-2-yl)cyclopropyl)-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.
