Chemical Structure
Description
The occurrence of 4-AMINO-P-TERPHENYL 7293-45-0 [1,1':4',1''-Terphenyl]-4-amine is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-AMINO-P-TERPHENYL 7293-45-0 [1,1':4',1''-Terphenyl]-4-amine (CAS 7293-45-0), molecular formula C18H33N and molecular weight 263.46 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-AMINO-P-TERPHENYL 7293-45-0 [1,1':4',1''-Terphenyl]-4-amine (C18H33N) is characterized by a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 4-AMINO-P-TERPHENYL 7293-45-0 [1,1':4',1''-Terphenyl]-4-amine 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.
