Chemical Structure
Description
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.
Tris[4'-(2-thienyl)-4-biphenylyl]amine (CAS 1092356-36-9), molecular formula C48H33NS3 and molecular weight 719.98 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Tris[4'-(2-thienyl)-4-biphenylyl]amine (C48H33NS3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), Tris[4'-(2-thienyl)-4-biphenylyl]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.
