4-Ethyl-3-{[(4-methylphenyl)methyl]sulfanyl}-5-{thieno[2,3-b]quinolin-2-yl}-4H-1,2,4-triazole CAS 439112-39-7 chemical structure

Description

The occurrence of 4-Ethyl-3-{[(4-methylphenyl)methyl]sulfanyl}-5-{thieno[2,3-b]quinolin-2-yl}-4H-1,2,4-triazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Ethyl-3-{[(4-methylphenyl)methyl]sulfanyl}-5-{thieno[2,3-b]quinolin-2-yl}-4H-1,2,4-triazole (CAS 439112-39-7) is a high-purity analytical reference standard with the molecular formula C23H20N4S2 and a molecular weight of 416.56 g/mol.

The molecular framework of 4-Ethyl-3-{[(4-methylphenyl)methyl]sulfanyl}-5-{thieno[2,3-b]quinolin-2-yl}-4H-1,2,4-triazole (C23H20N4S2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), 4-Ethyl-3-{[(4-methylphenyl)methyl]sulfanyl}-5-{thieno[2,3-b]quinolin-2-yl}-4H-1,2,4-triazole 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.
