Chemical Structure
Description
As a certified reference material (CRM), 4-Methyl-3-(methylthio)-5-(3-((3-(trifluoromethyl)benzyl)oxy)thiophen-2-yl)-4H-1,2,4-triazole 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.
4-Methyl-3-(methylthio)-5-(3-((3-(trifluoromethyl)benzyl)oxy)thiophen-2-yl)-4H-1,2,4-triazole (CAS 343376-19-2), molecular formula C16H14F3N3OS2 and molecular weight 385.43 g/mol, is a CATO reference standard with documented purity and traceability.
4-Methyl-3-(methylthio)-5-(3-((3-(trifluoromethyl)benzyl)oxy)thiophen-2-yl)-4H-1,2,4-triazole (C16H14F3N3OS2) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
