Chemical Structure
Description
3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (5-(4-(trifluoromethyl)phenyl)thiophen-2-yl)boronate (CAS 1402234-05-2) is a high-purity analytical reference standard with the molecular formula C17H20BF3O3S and a molecular weight of 372.21 g/mol.
The molecular framework of 3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (5-(4-(trifluoromethyl)phenyl)thiophen-2-yl)boronate (C17H20BF3O3S) is characterized by a steroid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
As a certified reference material (CRM), 3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (5-(4-(trifluoromethyl)phenyl)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.
