Chemical Structure
Description
As a certified reference material (CRM), 9-methyl-5-(((trifluoromethyl)sulfonyl)oxy)-2,3-dihydrobenzo[b]oxepin-8-yl pivalate 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.
9-methyl-5-(((trifluoromethyl)sulfonyl)oxy)-2,3-dihydrobenzo[b]oxepin-8-yl pivalate (CAS 2226905-38-8), molecular formula C17H19F3O6S and molecular weight 408.39 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 9-methyl-5-(((trifluoromethyl)sulfonyl)oxy)-2,3-dihydrobenzo[b]oxepin-8-yl pivalate (C17H19F3O6S) is characterized by a flavonoid core, a sulfone group, 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.
