Chemical Structure
Description
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.
(3S,4S)-4-Amino-1,1-dioxo-tetrahydro-1lambda*6*-thiophen-3-ol hydrochloride (CAS 1217652-76-0), molecular formula C4H9NO3SHCl and molecular weight 187.64 g/mol, is a CATO reference standard with documented purity and traceability.
(3S,4S)-4-Amino-1,1-dioxo-tetrahydro-1lambda*6*-thiophen-3-ol hydrochloride (C4H9NO3SHCl) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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.
As a certified reference material (CRM), (3S,4S)-4-Amino-1,1-dioxo-tetrahydro-1lambda*6*-thiophen-3-ol 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.
