Chemical Structure
Description
As a certified reference material (CRM), 2-[2-chloro-5-(trifluoromethyl)benzenesulfonamido]-4-(methylsulfanyl)butanoic acid 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-[2-chloro-5-(trifluoromethyl)benzenesulfonamido]-4-(methylsulfanyl)butanoic acid (CAS 1008945-26-3), a certified reference material (molecular formula C12H13ClF3NO4S2, MW 391.81 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/chlorine substitution, 2-[2-chloro-5-(trifluoromethyl)benzenesulfonamido]-4-(methylsulfanyl)butanoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 391.81 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.
