2,2',2''-(Benzene-1,3,5-triyltris(ethyne-2,1-diyl))tribenzaldehyde CAS 1993470-34-0 chemical structure

Description

The occurrence of 2,2',2''-(Benzene-1,3,5-triyltris(ethyne-2,1-diyl))tribenzaldehyde is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,2',2''-(Benzene-1,3,5-triyltris(ethyne-2,1-diyl))tribenzaldehyde (CAS 1993470-34-0) is a high-purity analytical reference standard with the molecular formula C33H18O3 and a molecular weight of 462.49 g/mol.

Structurally, 2,2',2''-(Benzene-1,3,5-triyltris(ethyne-2,1-diyl))tribenzaldehyde (C33H18O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 25.0, corresponding to approximately 25 ring(s) or double-bond equivalent(s). With a molecular weight of 462.49 g/mol, it falls into the moderately-high-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.
