Description
As a certified reference material (CRM), 2,3-Difluoro-4''-Heptyl-4-Pentyl-1,1':4',1''-Terphenyl 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.
2,3-Difluoro-4''-Heptyl-4-Pentyl-1,1':4',1''-Terphenyl (CAS 121218-85-7), molecular formula C30H38F2 and molecular weight 436.62 g/mol, is a CATO reference standard with documented purity and traceability.
2,3-Difluoro-4''-Heptyl-4-Pentyl-1,1':4',1''-Terphenyl (C30H38F2) contains fluorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
