Description
CATO supplies 2-Chloro-4-fluoro-1,3-dimethylbenzene (CAS 26829-81-2), a certified reference material (molecular formula C8H8ClF, MW 158.60 g/mol) for analytical method development and quality control.
The molecular framework of 2-Chloro-4-fluoro-1,3-dimethylbenzene (C8H8ClF) is characterized by fluorine/chlorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 2-Chloro-4-fluoro-1,3-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.
