4,4',4''-(Benzene-1,3,5-triyltris(ethyne-2,1-diyl))trianiline CAS 326002-91-9

Description

The occurrence of 4,4',4''-(Benzene-1,3,5-triyltris(ethyne-2,1-diyl))trianiline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4,4',4''-(Benzene-1,3,5-triyltris(ethyne-2,1-diyl))trianiline (CAS 326002-91-9), molecular formula C30H21N3 and molecular weight 423.51 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 4,4',4''-(Benzene-1,3,5-triyltris(ethyne-2,1-diyl))trianiline is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 423.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
