Chemical Structure
Description
As a certified reference material (CRM), 1,3,5-Trifluoro-2,4,6-tris(phenylethynyl)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.
1,3,5-Trifluoro-2,4,6-tris(phenylethynyl)benzene (CAS 674289-04-4) is a high-purity analytical reference standard with the molecular formula C30H15F3 and a molecular weight of 432.44 g/mol.
1,3,5-Trifluoro-2,4,6-tris(phenylethynyl)benzene (C30H15F3) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
