Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 182.21 g/mol gives (4-Fluorobenzo[b]thiophen-2-yl)methanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(4-Fluorobenzo[b]thiophen-2-yl)methanol (CAS 957059-61-9), molecular formula C9H7FOS and molecular weight 182.21 g/mol, is a CATO reference standard with documented purity and traceability.
(4-Fluorobenzo[b]thiophen-2-yl)methanol (C9H7FOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), (4-Fluorobenzo[b]thiophen-2-yl)methanol 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.
