N-[2-Chloro-5-(trifluoromethyl)phenyl]-2-[(1-methyl-1H-1,2,3,4-tetrazol-5-yl)sulfanyl]acetamide (CAS 303091-10-3), molecular formula C11H9ClF3N5OS and molecular weight 351.74 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, N-[2-Chloro-5-(trifluoromethyl)phenyl]-2-[(1-methyl-1H-1,2,3,4-tetrazol-5-yl)sulfanyl]acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 351.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures N-[2-Chloro-5-(trifluoromethyl)phenyl]-2-[(1-methyl-1H-1,2,3,4-tetrazol-5-yl)sulfanyl]acetamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
