1-Methyl-4-((4-propylphenyl)ethynyl)benzene CAS 184161-94-2

Description

Compared with other compounds in its class, the molecular weight of 234.34 g/mol gives 1-Methyl-4-((4-propylphenyl)ethynyl)benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-Methyl-4-((4-propylphenyl)ethynyl)benzene (CAS 184161-94-2), a certified reference material (molecular formula C18H18, MW 234.34 g/mol) for analytical method development and quality control.

Owing to a polycyclic aromatic system, 1-Methyl-4-((4-propylphenyl)ethynyl)benzene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 234.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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-Methyl-4-((4-propylphenyl)ethynyl)benzene 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.
