5-Methyl-[1,2,4]triazolo[4,3-a]quinoline-1-thiol CAS 35359-27-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Methyl-[1,2,4]triazolo[4,3-a]quinoline-1-thiol.

CATO supplies 5-Methyl-[1,2,4]triazolo[4,3-a]quinoline-1-thiol (CAS 35359-27-4), a certified reference material (molecular formula C11H9N3S, MW 215.27 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 5-Methyl-[1,2,4]triazolo[4,3-a]quinoline-1-thiol is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 215.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
