Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 287.40 g/mol gives Tri-p-tolylamine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Tri-p-tolylamine (CAS 1159-53-1) is a high-purity analytical reference standard with the molecular formula C21H21N and a molecular weight of 287.40 g/mol.
Structurally, Tri-p-tolylamine (C21H21N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 287.40 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.
As a certified reference material (CRM), Tri-p-tolylamine 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.
