Chemical Structure

Methyl (S)-5-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-((1,1,1-trifluoropropan-2-yl)oxy)benzoate CAS 2639835-82-6 chemical structure

Description

As a certified reference material (CRM), Methyl (S)-5-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-((1,1,1-trifluoropropan-2-yl)oxy)benzoate 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.

Methyl (S)-5-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-((1,1,1-trifluoropropan-2-yl)oxy)benzoate (CAS 2639835-82-6) is a high-purity analytical reference standard with the molecular formula C17H21BF4O5 and a molecular weight of 392.15 g/mol.

The molecular framework of Methyl (S)-5-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-((1,1,1-trifluoropropan-2-yl)oxy)benzoate (C17H21BF4O5) is characterized by a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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).

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.
