Chemical Structure
Description
Structurally, Trimethyl-d9-sulfoxonium Iodide (IC3D9OS) contains deuterium isotope labeling, sulfur-containing functionality, a hydroxyl group, an ether linkage, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 229.12 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Trimethyl-d9-sulfoxonium Iodide (CAS 23726-00-3), molecular formula IC3D9OS and molecular weight 229.12 g/mol, is a CATO reference standard with documented purity and traceability.
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.
