Bis(4-ethynylphenyl)methane CAS 6140-83-6 chemical structure

Description

Bis(4-ethynylphenyl)methane (CAS 6140-83-6) is a high-purity analytical reference standard with the molecular formula C16H11N and a molecular weight of 217.27 g/mol.

Bis(4-ethynylphenyl)methane (C16H11N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures Bis(4-ethynylphenyl)methane 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.
