Chemical Structure
Description
As a certified reference material (CRM), 1-((4-Bromo-3-fluorophenyl)sulfonyl)pyrrolidine 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 1-((4-Bromo-3-fluorophenyl)sulfonyl)pyrrolidine (CAS 1055995-83-9), a certified reference material (molecular formula C10H11BrFNO2S, MW 308.17 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, 1-((4-Bromo-3-fluorophenyl)sulfonyl)pyrrolidine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 308.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
