2-((4-Amino-5-oxo-4,5-dihydro-1,2,4-triazin-3-yl)thio)-N-(3-chloro-4-methylphenyl)acetamide (CAS 869068-27-9), molecular formula C12H12ClN5O2S and molecular weight 325.77 g/mol, is a CATO reference standard with documented purity and traceability.
2-((4-Amino-5-oxo-4,5-dihydro-1,2,4-triazin-3-yl)thio)-N-(3-chloro-4-methylphenyl)acetamide (C12H12ClN5O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 2-((4-Amino-5-oxo-4,5-dihydro-1,2,4-triazin-3-yl)thio)-N-(3-chloro-4-methylphenyl)acetamide 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.
