Compared with other compounds in its class, the molecular weight of 321.40 g/mol gives 2-((4-Amino-5-ethyl-4H-1,2,4-triazol-3-yl)thio)-N-(2-ethoxyphenyl)acetamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-((4-Amino-5-ethyl-4H-1,2,4-triazol-3-yl)thio)-N-(2-ethoxyphenyl)acetamide (CAS 877434-13-4), a certified reference material (molecular formula C14H19N5O2S, MW 321.40 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-((4-Amino-5-ethyl-4H-1,2,4-triazol-3-yl)thio)-N-(2-ethoxyphenyl)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 321.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 2-((4-Amino-5-ethyl-4H-1,2,4-triazol-3-yl)thio)-N-(2-ethoxyphenyl)acetamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
