Chemical Structure
Description
The occurrence of 1,5-Difluoro-2,4-dimethylbenzene is closely related to fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1,5-Difluoro-2,4-dimethylbenzene (CAS 63696-97-9), a certified reference material (molecular formula C8H8F2, MW 142.15 g/mol) for analytical method development and quality control.
The molecular framework of 1,5-Difluoro-2,4-dimethylbenzene (C8H8F2) is characterized by fluorine substitution, an aromatic ring system. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1,5-Difluoro-2,4-dimethylbenzene 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.
