2-{[4-ethyl-5-(2-methylphenyl)-4h-1,2,4-triazol-3-yl]sulfanyl}acetic acid CAS 741731-80-6

Description

The occurrence of 2-{[4-ethyl-5-(2-methylphenyl)-4h-1,2,4-triazol-3-yl]sulfanyl}acetic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-{[4-ethyl-5-(2-methylphenyl)-4h-1,2,4-triazol-3-yl]sulfanyl}acetic acid (CAS 741731-80-6) is a high-purity analytical reference standard with the molecular formula C13H15N3O2S and a molecular weight of 277.34 g/mol.

The molecular framework of 2-{[4-ethyl-5-(2-methylphenyl)-4h-1,2,4-triazol-3-yl]sulfanyl}acetic acid (C13H15N3O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 2-{[4-ethyl-5-(2-methylphenyl)-4h-1,2,4-triazol-3-yl]sulfanyl}acetic acid 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.
