Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 2-((5-ethyl-1H-1,2,4-triazol-3-yl)thio)acetate.
Ethyl 2-((5-ethyl-1H-1,2,4-triazol-3-yl)thio)acetate (CAS 449747-35-7), molecular formula C8H13N3O2S and molecular weight 215.27 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H13N3O2S, Ethyl 2-((5-ethyl-1H-1,2,4-triazol-3-yl)thio)acetate contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 215.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
