Chemical Structure
Description
The occurrence of 2-Ethyl-5-fluoropyridine is closely related to a nitrile group, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Ethyl-5-fluoropyridine (CAS 1934667-67-0) is a high-purity analytical reference standard with the molecular formula C7H8FN and a molecular weight of 125.14 g/mol.
2-Ethyl-5-fluoropyridine (C7H8FN) contains a nitrile group, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 2-Ethyl-5-fluoropyridine 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.
