Chemical Structure
Description
The occurrence of 2-Bromo-5-(difluoromethyl)thiophene is closely related to sulfur-containing functionality, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-Bromo-5-(difluoromethyl)thiophene (CAS 924646-90-2), a certified reference material (molecular formula C5H3BrF2S, MW 213.04 g/mol) for analytical method development and quality control.
2-Bromo-5-(difluoromethyl)thiophene (C5H3BrF2S) contains sulfur-containing functionality, fluorine/bromine substitution. Halogen substitution raises its density and boiling point; 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-Bromo-5-(difluoromethyl)thiophene 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.
