4-((1R,4r)-4-ethylcyclohexyl)-4'-((1s,4r)-4-propylcyclohexyl)-1,1'-biphenyl CAS 300545-17-9

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.

4-((1R,4r)-4-ethylcyclohexyl)-4'-((1s,4r)-4-propylcyclohexyl)-1,1'-biphenyl (CAS 300545-17-9), molecular formula C29H40 and molecular weight 388.63 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-((1R,4r)-4-ethylcyclohexyl)-4'-((1s,4r)-4-propylcyclohexyl)-1,1'-biphenyl (C29H40) is characterized by a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures 4-((1R,4r)-4-ethylcyclohexyl)-4'-((1s,4r)-4-propylcyclohexyl)-1,1'-biphenyl under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
