Chemical Structure
Description
1,3,5-Tri(4-pyridyl)benzene (CAS 170165-84-1) is a high-purity analytical reference standard with the molecular formula C21H15N3 and a molecular weight of 309.36 g/mol.
1,3,5-Tri(4-pyridyl)benzene (C21H15N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), 1,3,5-Tri(4-pyridyl)benzene 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.
