Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 253.38 g/mol gives 4-(tert-Butyl)-N-(4-ethylphenyl)aniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-(tert-Butyl)-N-(4-ethylphenyl)aniline (CAS 642473-66-3), a certified reference material (molecular formula C18H23N, MW 253.38 g/mol) for analytical method development and quality control.
Structurally, 4-(tert-Butyl)-N-(4-ethylphenyl)aniline (C18H23N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 253.38 g/mol, it falls into the medium-molecular-weight range. 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.
