Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO supplies 3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (5-(3,5-difluorophenyl)thiophen-2-yl)boronate (CAS 1402227-88-6), a certified reference material (molecular formula C16H19BF2O3S, MW 340.19 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (5-(3,5-difluorophenyl)thiophen-2-yl)boronate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 340.19 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), 3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (5-(3,5-difluorophenyl)thiophen-2-yl)boronate 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.
