Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 295.53 g/mol gives 7-Chloro-6-iodothieno[3,2-b]pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 7-Chloro-6-iodothieno[3,2-b]pyridine (CAS 1595635-51-0), a certified reference material (molecular formula C7H3ClINS, MW 295.53 g/mol) for analytical method development and quality control.
The molecular framework of 7-Chloro-6-iodothieno[3,2-b]pyridine (C7H3ClINS) is characterized by a nitrile group, sulfur-containing functionality, chlorine/iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), 7-Chloro-6-iodothieno[3,2-b]pyridine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
