2-(Difluoromethyl)-4-iodothiophene CAS 2091118-96-4

Description

The occurrence of 2-(Difluoromethyl)-4-iodothiophene is closely related to sulfur-containing functionality, fluorine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-(Difluoromethyl)-4-iodothiophene (CAS 2091118-96-4), a certified reference material (molecular formula C5H3F2IS, MW 260.04 g/mol) for analytical method development and quality control.

Structurally, 2-(Difluoromethyl)-4-iodothiophene (C5H3F2IS) contains sulfur-containing functionality, fluorine/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 260.04 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.
