Chemical Structure
Description
The molecular framework of n-Allyl-2-chloro-5-(trifluoromethyl)benzenesulfonamide (C10H9ClF3NO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
n-Allyl-2-chloro-5-(trifluoromethyl)benzenesulfonamide (CAS 757221-31-1), molecular formula C10H9ClF3NO2S and molecular weight 299.70 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), n-Allyl-2-chloro-5-(trifluoromethyl)benzenesulfonamide 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.
