Description

The occurrence of 3,5,7-Trichlorothieno[3,2-b]pyridine is closely related to a nitrile group, sulfur-containing functionality, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3,5,7-Trichlorothieno[3,2-b]pyridine (CAS 2476729-57-2), molecular formula C7H2Cl3NS and molecular weight 238.52 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H2Cl3NS, 3,5,7-Trichlorothieno[3,2-b]pyridine contains a nitrile group, sulfur-containing functionality, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 238.52 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.
