Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 221.70 g/mol gives (S)-3-Amino-4-(thiophen-2-yl)butanoic acid hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (S)-3-Amino-4-(thiophen-2-yl)butanoic acid hydrochloride (CAS 332061-90-2), a certified reference material (molecular formula C8H11NO2SHCl, MW 221.70 g/mol) for analytical method development and quality control.
(S)-3-Amino-4-(thiophen-2-yl)butanoic acid hydrochloride (C8H11NO2SHCl) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), (S)-3-Amino-4-(thiophen-2-yl)butanoic acid hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
