Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO supplies 5-(trans-4-(2-(trans-4-Ethylcyclohexyl)ethyl)-cyclohexyl)-1,2,3-trifluorobenzene (CAS 137529-57-8), a certified reference material (molecular formula C22H31F3, MW 352.48 g/mol) for analytical method development and quality control.
5-(trans-4-(2-(trans-4-Ethylcyclohexyl)ethyl)-cyclohexyl)-1,2,3-trifluorobenzene (C22H31F3) contains fluorine substitution, an aromatic ring 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 5-(trans-4-(2-(trans-4-Ethylcyclohexyl)ethyl)-cyclohexyl)-1,2,3-trifluorobenzene 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.
