Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-Amino-1-(thiophen-2-yl)butan-1-one hydrochloride (CAS 1423026-29-2) is a high-purity analytical reference standard with the molecular formula C8H11NOSHCl and a molecular weight of 205.70 g/mol.
Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, 3-Amino-1-(thiophen-2-yl)butan-1-one hydrochloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 205.70 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.
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.
