Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 213.72 g/mol gives (r)-1-(Benzo[b]thiophen-3-yl)ethanamine hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(r)-1-(Benzo[b]thiophen-3-yl)ethanamine hydrochloride (CAS 1027709-85-8) is a high-purity analytical reference standard with the molecular formula C10H11NSHCl and a molecular weight of 213.72 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, (r)-1-(Benzo[b]thiophen-3-yl)ethanamine hydrochloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 213.72 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
