Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromotetrahydrothiopyran 1,1-Dioxide.
4-Bromotetrahydrothiopyran 1,1-Dioxide (CAS 38690-84-5), molecular formula C5H9BrO2S and molecular weight 213.09 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C5H9BrO2S, 4-Bromotetrahydrothiopyran 1,1-Dioxide contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 213.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
