Description
As a certified reference material (CRM), (E)-[(2-Chlorophenyl)methoxy]({2-[(4-chlorophenyl)sulfanyl]-1-{6-methyl-[1,2,4]triazolo[3,2-b][1,3]thiazol-5-yl}ethylidene})amine 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.
(E)-[(2-Chlorophenyl)methoxy]({2-[(4-chlorophenyl)sulfanyl]-1-{6-methyl-[1,2,4]triazolo[3,2-b][1,3]thiazol-5-yl}ethylidene})amine (CAS 866131-20-6), molecular formula C20H16Cl2N4OS2 and molecular weight 463.40 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, (E)-[(2-Chlorophenyl)methoxy]({2-[(4-chlorophenyl)sulfanyl]-1-{6-methyl-[1,2,4]triazolo[3,2-b][1,3]thiazol-5-yl}ethylidene})amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 463.40 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.
