Chemical Structure
Description
As a certified reference material (CRM), 2,5-Dibromo-3-butylthiophene 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.
CATO supplies 2,5-Dibromo-3-butylthiophene (CAS 116971-10-9), a certified reference material (molecular formula C8H10Br2S, MW 298.04 g/mol) for analytical method development and quality control.
2,5-Dibromo-3-butylthiophene (C8H10Br2S) contains sulfur-containing functionality, 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.
