Chemical Structure
Description
The molecular framework of (S)-3-Amino-4-(3-thienyl)butanoic acid hydrochloride (C8H11NO2SHCl) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
(S)-3-Amino-4-(3-thienyl)butanoic acid hydrochloride (CAS 270262-99-2) is a high-purity analytical reference standard with the molecular formula C8H11NO2SHCl and a molecular weight of 221.70 g/mol.
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.
