Compared with other compounds in its class, the molecular weight of 268.18 g/mol gives 3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (3-cyclopropylthiophen-2-yl)boronate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (3-cyclopropylthiophen-2-yl)boronate (CAS 2223033-79-0), a certified reference material (molecular formula C13H21BO3S, MW 268.18 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (3-cyclopropylthiophen-2-yl)boronate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 268.18 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
