Chemical Structure
Description
As a certified reference material (CRM), 4-Amino-2,2-dimethyltetrahydro-2H-thiopyran 1,1-dioxide 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.
4-Amino-2,2-dimethyltetrahydro-2H-thiopyran 1,1-dioxide hydrochloride (CAS 2138258-74-7) is a high-purity analytical reference standard with the molecular formula C7H15NO2SHCl and a molecular weight of 213.72 g/mol.
4-Amino-2,2-dimethyltetrahydro-2H-thiopyran 1,1-dioxide hydrochloride (C7H15NO2SHCl) 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.
