Description
CATO manufactures 1-Bromo-3-(difluoromethyl)cyclobut-1-ene 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-Bromo-3-(difluoromethyl)cyclobut-1-ene (CAS 2452341-92-1), molecular formula C5H5BrF2 and molecular weight 182.99 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Bromo-3-(difluoromethyl)cyclobut-1-ene (C5H5BrF2) is characterized by fluorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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.
