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.
(1S,4S)-2λ⁶-thia-5-azabicyclo[2.2.1]heptane 2,2-dioxide;hydrochloride (CAS 1481613-21-1), molecular formula C5H9NO2SHCl and molecular weight 183.65 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (1S,4S)-2λ⁶-thia-5-azabicyclo[2.2.1]heptane 2,2-dioxide;hydrochloride (C5H9NO2SHCl) 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.
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.
