Chemical Structure
Description
The occurrence of 3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (3-acetylthiophen-2-yl)boronate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (3-acetylthiophen-2-yl)boronate (CAS 2223033-77-8), a certified reference material (molecular formula C12H19BO4S, MW 270.15 g/mol) for analytical method development and quality control.
The molecular framework of 3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (3-acetylthiophen-2-yl)boronate (C12H19BO4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), 3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (3-acetylthiophen-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.
