5-{thieno[2,3-b]quinolin-2-yl}-1,3,4-oxadiazole-2-thiol CAS 439112-41-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-{thieno[2,3-b]quinolin-2-yl}-1,3,4-oxadiazole-2-thiol.

CATO supplies 5-{thieno[2,3-b]quinolin-2-yl}-1,3,4-oxadiazole-2-thiol (CAS 439112-41-1), a certified reference material (molecular formula C13H7N3OS2, MW 285.34 g/mol) for analytical method development and quality control.

5-{thieno[2,3-b]quinolin-2-yl}-1,3,4-oxadiazole-2-thiol (C13H7N3OS2) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

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.
