Chemical Structure

2,3',4',5'-Tetrafluoro-4-(4-pentylcyclohexyl)-1,1'-biphenyl CAS 173837-36-0 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 2,3',4',5'-Tetrafluoro-4-(4-pentylcyclohexyl)-1,1'-biphenyl.

CATO supplies 2,3',4',5'-Tetrafluoro-4-(4-pentylcyclohexyl)-1,1'-biphenyl (CAS 173837-36-0), a certified reference material (molecular formula C23H26F4, MW 378.45 g/mol) for analytical method development and quality control.

Structurally, 2,3',4',5'-Tetrafluoro-4-(4-pentylcyclohexyl)-1,1'-biphenyl (C23H26F4) contains fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 378.45 g/mol, it falls into the moderately-high-molecular-weight range. 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), 2,3',4',5'-Tetrafluoro-4-(4-pentylcyclohexyl)-1,1'-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.
