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 Methyl 4-(2-((4-ethyl-5-(furan-2-yl)-4H-1,2,4-triazol-3-yl)thio)acetamido)benzoate.
Methyl 4-(2-((4-ethyl-5-(furan-2-yl)-4H-1,2,4-triazol-3-yl)thio)acetamido)benzoate (CAS 557069-77-9), molecular formula C18H18N4O4S and molecular weight 386.42 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Methyl 4-(2-((4-ethyl-5-(furan-2-yl)-4H-1,2,4-triazol-3-yl)thio)acetamido)benzoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 386.42 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.
As a certified reference material (CRM), Methyl 4-(2-((4-ethyl-5-(furan-2-yl)-4H-1,2,4-triazol-3-yl)thio)acetamido)benzoate 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.
