Compared with other compounds in its class, the molecular weight of 189.28 g/mol gives 2-(Quinolin-2-yl)ethane-1-thiol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(Quinolin-2-yl)ethane-1-thiol (CAS 218276-33-6) is a high-purity analytical reference standard with the molecular formula C11H11NS and a molecular weight of 189.28 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 2-(Quinolin-2-yl)ethane-1-thiol is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 189.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
