Description
CATO supplies 4,4,5,5-Tetramethyl-2-(4-((3-(trifluoromethyl)benzyl)oxy)phenyl)-1,3,2-dioxaborolane (CAS 1813554-41-4), a certified reference material (molecular formula C20H22BF3O3, MW 378.19 g/mol) for analytical method development and quality control.
Structurally, 4,4,5,5-Tetramethyl-2-(4-((3-(trifluoromethyl)benzyl)oxy)phenyl)-1,3,2-dioxaborolane (C20H22BF3O3) contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.5, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 378.19 g/mol, it falls into the moderately-high-molecular-weight range. 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).
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.
CATO manufactures 4,4,5,5-Tetramethyl-2-(4-((3-(trifluoromethyl)benzyl)oxy)phenyl)-1,3,2-dioxaborolane 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.
