Description
CATO manufactures 1,4-Difluoro-2-(isopropylsulfonyl)benzene 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.
1,4-Difluoro-2-(isopropylsulfonyl)benzene (CAS 2879334-89-9), molecular formula C9H10F2O2S and molecular weight 220.24 g/mol, is a CATO reference standard with documented purity and traceability.
1,4-Difluoro-2-(isopropylsulfonyl)benzene (C9H10F2O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
