Description
As a certified reference material (CRM), Bis(4-fluorophenyl)methane 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.
CATO supplies Bis(4-fluorophenyl)methane (CAS 457-68-1), a certified reference material (molecular formula C13H10F2, MW 204.22 g/mol) for analytical method development and quality control.
Owing to fluorine substitution, an aromatic ring system, Bis(4-fluorophenyl)methane is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 204.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
