3-(iodomethyl)-1λ⁶-thietane-1,1-dione CAS 1784319-34-1

Description

The occurrence of 3-(iodomethyl)-1λ⁶-thietane-1,1-dione is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(iodomethyl)-1λ⁶-thietane-1,1-dione (CAS 1784319-34-1), molecular formula C4H7IO2S and molecular weight 246.07 g/mol, is a CATO reference standard with documented purity and traceability.

3-(iodomethyl)-1λ⁶-thietane-1,1-dione (C4H7IO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine 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.

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.
