Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,4＇-Di-Tert-Butyl-2,2＇-Bipyridyl.
4,4＇-Di-Tert-Butyl-2,2＇-Bipyridyl (CAS 72914-19-3), molecular formula C18H24N2 and molecular weight 268.40 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C18H24N2, 4,4＇-Di-Tert-Butyl-2,2＇-Bipyridyl contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 268.40 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 4,4＇-Di-Tert-Butyl-2,2＇-Bipyridyl 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.
