2-(4-Ethyl-5-((3-fluoropropyl)thio)-4H-1,2,4-triazol-3-yl)thieno[2,3-b]quinoline CAS 439112-40-0

Description

The occurrence of 2-(4-Ethyl-5-((3-fluoropropyl)thio)-4H-1,2,4-triazol-3-yl)thieno[2,3-b]quinoline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(4-Ethyl-5-((3-fluoropropyl)thio)-4H-1,2,4-triazol-3-yl)thieno[2,3-b]quinoline (CAS 439112-40-0), molecular formula C18H17FN4S2 and molecular weight 372.48 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution, 2-(4-Ethyl-5-((3-fluoropropyl)thio)-4H-1,2,4-triazol-3-yl)thieno[2,3-b]quinoline is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 372.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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-((3-fluoropropyl)thio)-4H-1,2,4-triazol-3-yl)thieno[2,3-b]quinoline 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.
