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 3-Iodo-2,4,5-trimethylthiophene.
CATO supplies 3-Iodo-2,4,5-trimethylthiophene (CAS 60813-84-5), a certified reference material (molecular formula C7H9IS, MW 252.12 g/mol) for analytical method development and quality control.
Structurally, 3-Iodo-2,4,5-trimethylthiophene (C7H9IS) contains sulfur-containing functionality, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 252.12 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
