Chemical Structure

2,4-Diiodothiophene CAS 19259-06-4 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 2,4-Diiodothiophene.

2,4-Diiodothiophene (CAS 19259-06-4), molecular formula C4H2I2S and molecular weight 335.93 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C4H2I2S, 2,4-Diiodothiophene contains sulfur-containing functionality, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 335.93 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.

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.
