Ethyl 2-((5-((4-fluorobenzamido)methyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)acetate CAS 338962-50-8 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-((4-fluorobenzamido)methyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)acetate.

Ethyl 2-((5-((4-fluorobenzamido)methyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)acetate (CAS 338962-50-8), molecular formula C20H19FN4O3S and molecular weight 414.45 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, Ethyl 2-((5-((4-fluorobenzamido)methyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)acetate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 414.45 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), Ethyl 2-((5-((4-fluorobenzamido)methyl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)acetate 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.
