Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (5-(4-fluoro-2-methylphenyl)thiophen-2-yl)boronate (CAS 1402227-73-9), molecular formula C17H22BFO3S and molecular weight 336.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (5-(4-fluoro-2-methylphenyl)thiophen-2-yl)boronate (C17H22BFO3S) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (5-(4-fluoro-2-methylphenyl)thiophen-2-yl)boronate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
