Chemical Structure
Description
3-Amino-2-[(thiophen-2-yl)methyl]propanoic acid hydrochloride (CAS 1423032-25-0) is a high-purity analytical reference standard with the molecular formula C8H11NO2SHCl and a molecular weight of 221.70 g/mol.
Based on its molecular formula C8H11NO2SHCl, 3-Amino-2-[(thiophen-2-yl)methyl]propanoic acid hydrochloride contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 221.70 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 3-Amino-2-[(thiophen-2-yl)methyl]propanoic 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.
