Chemical Structure

1,4-Bis[2-(4-butylphenyl)ethynyl]-2-cyclopropylbenzene CAS 1282582-89-1 chemical structure

Description

CATO supplies 1,4-Bis[2-(4-butylphenyl)ethynyl]-2-cyclopropylbenzene (CAS 1282582-89-1), a certified reference material (molecular formula C33H34, MW 430.62 g/mol) for analytical method development and quality control.

Based on its molecular formula C33H34, 1,4-Bis[2-(4-butylphenyl)ethynyl]-2-cyclopropylbenzene contains a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 430.62 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 1,4-Bis[2-(4-butylphenyl)ethynyl]-2-cyclopropylbenzene 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.
