4-Phenyl-5-((quinolin-8-yloxy)methyl)-4H-1,2,4-triazole-3-thiol CAS 73511-58-7

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.

CATO supplies 4-Phenyl-5-((quinolin-8-yloxy)methyl)-4H-1,2,4-triazole-3-thiol (CAS 73511-58-7), a certified reference material (molecular formula C18H14N4OS, MW 334.39 g/mol) for analytical method development and quality control.

Structurally, 4-Phenyl-5-((quinolin-8-yloxy)methyl)-4H-1,2,4-triazole-3-thiol (C18H14N4OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 334.39 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
