Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 168.14 g/mol gives 4,6-Difluoro-1-indanone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4,6-Difluoro-1-indanone (CAS 162548-73-4), a certified reference material (molecular formula C9H6F2O, MW 168.14 g/mol) for analytical method development and quality control.
Structurally, 4,6-Difluoro-1-indanone (C9H6F2O) contains a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 168.14 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 4,6-Difluoro-1-indanone 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.
