Description
As a certified reference material (CRM), 4-Methoxy-3'-methylbiphenyl 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.
4-Methoxy-3'-methylbiphenyl (CAS 72093-48-2), molecular formula C13H11FO and molecular weight 202.22 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C13H11FO, 4-Methoxy-3'-methylbiphenyl contains a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 202.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
