Chemical Structure

(trans,trans)-4-(p-Tolyl)-4'-vinyl-1,1'-bi(cyclohexane) CAS 155041-85-3 chemical structure

Description

As a certified reference material (CRM), (trans,trans)-4-(p-Tolyl)-4'-vinyl-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.

CATO supplies (trans,trans)-4-(p-Tolyl)-4'-vinyl-1,1'-bi(cyclohexane) (CAS 155041-85-3), a certified reference material (molecular formula C21H30, MW 282.46 g/mol) for analytical method development and quality control.

Structurally, (trans,trans)-4-(p-Tolyl)-4'-vinyl-1,1'-bi(cyclohexane) (C21H30) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 282.46 g/mol, it falls into the medium-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.
