3-Bromo-5-(difluoromethyl)-2-methylthiophene CAS 2091602-53-6 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 3-Bromo-5-(difluoromethyl)-2-methylthiophene (CAS 2091602-53-6), a certified reference material (molecular formula C6H5BrF2S, MW 227.07 g/mol) for analytical method development and quality control.

3-Bromo-5-(difluoromethyl)-2-methylthiophene (C6H5BrF2S) 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.

As a certified reference material (CRM), 3-Bromo-5-(difluoromethyl)-2-methylthiophene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
