Chemical Structure
Description
4-Fluoro-6-vinyl-2,3-dihydro-1H-inden-1-one (CAS 1637453-48-5), molecular formula C11H9FO and molecular weight 176.19 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 4-Fluoro-6-vinyl-2,3-dihydro-1H-inden-1-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 176.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 4-Fluoro-6-vinyl-2,3-dihydro-1H-inden-1-one 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.
