Description
CATO manufactures 1-(2,5-Difluorophenyl)butan-1-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
1-(2,5-Difluorophenyl)butan-1-one (CAS 55787-96-7) is a high-purity analytical reference standard with the molecular formula C10H10F2O and a molecular weight of 184.18 g/mol.
The molecular framework of 1-(2,5-Difluorophenyl)butan-1-one (C10H10F2O) is characterized by a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
