Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(trans-4-Pentylcyclohexyl)-2-fluoro-4'-(trans-4-propylcyclohexyl)biphenyl.
4-(trans-4-Pentylcyclohexyl)-2-fluoro-4'-(trans-4-propylcyclohexyl)biphenyl (CAS 106349-49-9), molecular formula C32H45F and molecular weight 448.70 g/mol, is a CATO reference standard with documented purity and traceability.
4-(trans-4-Pentylcyclohexyl)-2-fluoro-4'-(trans-4-propylcyclohexyl)biphenyl (C32H45F) 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.
As a certified reference material (CRM), 4-(trans-4-Pentylcyclohexyl)-2-fluoro-4'-(trans-4-propylcyclohexyl)biphenyl 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.
