Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2-((4-Fluorophenyl)ethynyl)phenyl)ethan-1-one.
1-(2-((4-Fluorophenyl)ethynyl)phenyl)ethan-1-one (CAS 1426258-82-3) is a high-purity analytical reference standard with the molecular formula C16H11FO and a molecular weight of 238.26 g/mol.
Structurally, 1-(2-((4-Fluorophenyl)ethynyl)phenyl)ethan-1-one (C16H11FO) contains a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 238.26 g/mol, it falls into the medium-molecular-weight range. 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), 1-(2-((4-Fluorophenyl)ethynyl)phenyl)ethan-1-one 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.
