Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 156.17 g/mol gives 1,3-Difluoro-5-Isopropyl-Benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1,3-Difluoro-5-Isopropyl-Benzene (CAS 117358-53-9), a certified reference material (molecular formula C9H10F2, MW 156.17 g/mol) for analytical method development and quality control.
1,3-Difluoro-5-Isopropyl-Benzene (C9H10F2) contains 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), 1,3-Difluoro-5-Isopropyl-Benzene 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.
