Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 187.03 g/mol gives 4-Bromo-1,1-difluoro-3-methylbutane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Bromo-1,1-difluoro-3-methylbutane (CAS 1783578-17-5), a certified reference material (molecular formula C5H9BrF2, MW 187.03 g/mol) for analytical method development and quality control.
The molecular framework of 4-Bromo-1,1-difluoro-3-methylbutane (C5H9BrF2) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
