4-Ethyl-5-{4H,5H-naphtho[1,2-b]thiophen-2-yl}-4H-1,2,4-triazole-3-thiol CAS 477869-75-3

Description

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.

4-Ethyl-5-{4H,5H-naphtho[1,2-b]thiophen-2-yl}-4H-1,2,4-triazole-3-thiol (CAS 477869-75-3) is a high-purity analytical reference standard with the molecular formula C16H15N3S2 and a molecular weight of 313.44 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 4-Ethyl-5-{4H,5H-naphtho[1,2-b]thiophen-2-yl}-4H-1,2,4-triazole-3-thiol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 313.44 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
