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 1,3-Dithiol-1-ium iodide.
CATO supplies 1,3-Dithiol-1-ium iodide (CAS 1863-66-7), a certified reference material (molecular formula IC3H3S2, MW 230.08 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, iodine substitution, 1,3-Dithiol-1-ium iodide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 230.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
