3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (5-(dimethylamino)thiophen-2-yl)boronate CAS 2223032-09-3

Description

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.

3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (5-(dimethylamino)thiophen-2-yl)boronate (CAS 2223032-09-3), molecular formula C12H22BNO3S and molecular weight 271.18 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (5-(dimethylamino)thiophen-2-yl)boronate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 271.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
