Chemical Structure
Description
The occurrence of 4,4'-((2-Methyl-2-((pyridin-4-yloxy)methyl)propane-1,3-diyl)bis(oxy))dipyridine is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4,4'-((2-Methyl-2-((pyridin-4-yloxy)methyl)propane-1,3-diyl)bis(oxy))dipyridine (CAS 1228960-86-8) is a high-purity analytical reference standard with the molecular formula C20H21N3O3 and a molecular weight of 351.40 g/mol.
The molecular framework of 4,4'-((2-Methyl-2-((pyridin-4-yloxy)methyl)propane-1,3-diyl)bis(oxy))dipyridine (C20H21N3O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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).
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'-((2-Methyl-2-((pyridin-4-yloxy)methyl)propane-1,3-diyl)bis(oxy))dipyridine 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.
