Chemical Structure

(trans,trans)-4-Butyl-4-(4-fluorophenyl)-1,1-bi(cyclohexane) CAS 82832-28-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (trans,trans)-4-Butyl-4-(4-fluorophenyl)-1,1-bi(cyclohexane).

CATO supplies (trans,trans)-4-Butyl-4-(4-fluorophenyl)-1,1-bi(cyclohexane) (CAS 82832-28-8), a certified reference material (molecular formula C22H33F, MW 316.50 g/mol) for analytical method development and quality control.

(trans,trans)-4-Butyl-4-(4-fluorophenyl)-1,1-bi(cyclohexane) (C22H33F) 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), (trans,trans)-4-Butyl-4-(4-fluorophenyl)-1,1-bi(cyclohexane) 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.
