Chemical Structure
Description
1-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)methyl)-3-(2-phenoxyphenyl)thiourea (CAS 326815-41-2), molecular formula C20H15ClF3N3OS and molecular weight 437.87 g/mol, is a CATO reference standard with documented purity and traceability.
1-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)methyl)-3-(2-phenoxyphenyl)thiourea (C20H15ClF3N3OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine 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. 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.
As a certified reference material (CRM), 1-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)methyl)-3-(2-phenoxyphenyl)thiourea 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.
