5-((2-Chloro-4-fluorophenoxy)methyl)-4-methyl-4H-1,2,4-triazole-3-thiol CAS 725217-82-3

Description

5-((2-Chloro-4-fluorophenoxy)methyl)-4-methyl-4H-1,2,4-triazole-3-thiol (CAS 725217-82-3), molecular formula C10H9ClFN3OS and molecular weight 273.71 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, 5-((2-Chloro-4-fluorophenoxy)methyl)-4-methyl-4H-1,2,4-triazole-3-thiol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 273.71 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.

As a certified reference material (CRM), 5-((2-Chloro-4-fluorophenoxy)methyl)-4-methyl-4H-1,2,4-triazole-3-thiol 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.
